            The issue had to do with ords and ord normalization in sort-missing-last.
            Here's a patch with tests and a rewritten MissingLastOrdComparator that manipulates ord values rather than trying to just handle nulls.

            note: not all tests pass yet.

            OK, here's the final patch with all tests passing.

            Yonik: just to be verify: was this bug was introduced in Solr 1.4? ... presumably because of the changes to per segment collecting?

            (that's the way the "Affects Version/s" is marked, but i want to sanity check in case it was actually a more fundamental problem affecting earlier versions of Solr as well).

            Yep. The per-segment collecting and the FieldComparator changes caused us to rewrite all of our custom comparators... and this one had bugs.

            Then it was a different bug. This code was all new for 1.4
            Was it reproducible, and was a bug report filed? Can it still be reproduced?
