First screen on my system with that test ends at Sally Pheasant. One roll
gets to Frank Phebas. (Okay, it's a pretty big database...)

The solution we're using involves maintaining two fields for a person's name,
one formated and cased as the person wants to see it, and a second field that
is hidden from users that is maintained in all upper case, with the last word
from the formatted field (before any commas) placed first in the field hidden
field. The hidden field is used for all the sorting and searching.
