How to specify default order by clause in relations

To fix this issue As you wrote you want to 'order your results'. Schema is not a right place for that. You do it in a query.
You didn't paste your full schema I guess. I assumed that you have created_at field in comment class (if not, try using Timestampable behavior):
  ->select('n.*, c.*')
  ->from('newsFeed n')
  ->innerJoin('n.comment c')
  ->orderBy('c.created_at DESC');

AND order_no > $whatever_order_no_was_deleted

like below fixes the issue The generic type in dataviews often resolve to the current record.
In CRRelationsList class the generic type is named TNoteField:
public class CRRelationsList<TNoteField> : PXSelect<CRRelation>
    where TNoteField : IBqlField
protected virtual void CRRelation_RefNoteID_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
    // Get a cache object of type CROpportunity
    var refCache = sender.Graph.Caches[BqlCommand.GetItemType(typeof(TNoteField))];

    // Get the NoteID field value of the current CROpportunity object
    e.NewValue = refCache.GetValue(refCache.Current, typeof(TNoteField).Name);
// In a graph extension (PXGraphExtension)
Base.Caches[typeof(DAC)].Current.Fied = ???;

// Or in graph (PXGraph)
Caches[typeof(DAC)].Current.Fied = ???;
private static PXSelectDelegate GetHandler()
    return () =>
        var command = new Select2<CRRelation,
            LeftJoin<BAccount, On<BAccount.bAccountID, Equal<CRRelation.entityID>>,
                        On<Contact.contactID, Equal<Switch<Case<Where<BAccount.type, Equal<BAccountType.employeeType>>, BAccount.defContactID>, CRRelation.contactID>>>,
            LeftJoin<Users, On<Users.pKID, Equal<Contact.userID>>>>>,
            Where<CRRelation.refNoteID, Equal<Current<TNoteField>>>>();

        var startRow = PXView.StartRow;
        int totalRows = 0;
        var list = new PXView(PXView.CurrentGraph, false, command).
            Select(null, null, PXView.Searches, PXView.SortColumns, PXView.Descendings, PXView.Filters,
                    ref startRow, PXView.MaximumRows, ref totalRows);
        PXView.StartRow = 0;
        foreach (PXResult<CRRelation, BAccount, Contact, Users> row in list)
            var relation = (CRRelation)row[typeof(CRRelation)];
            var account = (BAccount)row[typeof(BAccount)];
            relation.Name = account.AcctName;
            relation.EntityCD = account.AcctCD;
            var contact = (Contact)row[typeof(Contact)];
            if (contact.ContactID == null && relation.ContactID != null &&
                account.Type != BAccountType.EmployeeType)
                var directContact = (Contact)PXSelect<Contact>.
                                                    Search<Contact.contactID>(PXView.CurrentGraph, relation.ContactID);
                if (directContact != null) contact = directContact;
            relation.Email = contact.EMail;
            var user = (Users)row[typeof(Users)];
            if (account.Type != BAccountType.EmployeeType)
                relation.ContactName = contact.DisplayName;
                if (string.IsNullOrEmpty(relation.Name))
                    relation.Name = user.FullName;
                if (string.IsNullOrEmpty(relation.Email))
                    relation.Email = user.Email;
        return list;
