Somebody contributed a patch for the secondary sort stuff a while back.
Whether it still works with 2.3.0 is a good question.

I also remember a *long* time ago (back when I was first starting with
zope about a year ago) someone posting a method for picking up all
the records in a catalog with a blank value for a field.  How you'd
find it in the mail archives, though, I have no clue, nor do I
remember what the method involved.
