Solved.  From perldelta (I'm running 5.6):

       Enhanced support for sort() subroutines

       Perl subroutines with a prototype of `($$)', and XSUBs in
       general, can now be used as sort subroutines.  In either
       case, the two elements to be compared are passed as normal
       parameters in @_.  See the sort entry in the perlfunc man­
       page.

target_cmp was prototyped, so it was comparing $a and $b which are not
passed to it!
