Update: realized too late that you understood the reason, nevertheless may this answer stand here for others as slow as myself in understanding written english :)
perldoc perlvar :)
$a $b Special package variables when using sort(), see "sort" in perlfunc. Because of this specialness $a and $b don't need to be declared (using local(), use vars, or our()) even when using the strict vars pragma. Don't lexicalize them with "my $a" or "my $b" if you want to be able to use them in the sort() comparison block or function.
