You are prototyping your anonymous subroutine definitions. The perlsub documentation seems to say that prototypes have no effect with such subs. Can you say what is happening here? Is this something peculiar to the sort builtin?

Also, sort doesn't seem to work properly with a code reference (which I take $sort_routine to be) as its first argument (tested on 5.8.2). Is this something new in 5.10?
