A question,

You can eliminate calling $s as a function (and the argument passing) and it will still work for the test cases i've been using. Is there a reason not to do that? That is, is there a reason to use the full function call when passing the function ref will work?

If you pulled that out, you would get:

#23456789012345678901234567890123456789012345
$x=0;$s=shift;$x={$_,[$x,0]}for sort$s @_;%$x
