Yeah, if I change it to ORDER BY alias3.lastname, nullnamesb.id;
instead of ORDER BY alias3.*, nullnamesb.id; then the tie break using
btint4fastcmp() is called more often.  It's also getting called with
the missing 4s which I mentioned upthread.

See the two outputs.  That points me towards something weird going on
in record_cmp().
