Bizarre indeed. I can't replicate it myself - with both the questions in the XML export I posted earlier the output lines change order if I swap the print statements. If you Check an unchanged answer you get the same grading output as before but I've never seen that mechanism fail to notice the changed answer. It uses (via arrays_same_at_key_missing_is_blank) a full string equality test.
