Why, oh why would you want to do numeric sorting without the numeric comparison operator? Interview question? Failure of communication? XY Problem? In any event, maybe something like this:
>perl -wMstrict -le
"my %jetsons = (
7 => 'Judy',
10 => 'Jane',
11 => 'George',
2 => 'Elroy',
100=> 'Rosey',
1 => 'Astro',
19 => 'Mr. Spacely',
22 => 'Mr. Cogswell'
);
;;
my @sorted = sort non_spaceship keys %jetsons;
print qq{@sorted};
;;
sub non_spaceship { return $a < $b ? -1 : $a > $b ? 1 : 0 }
"
1 2 7 10 11 19 22 100
