I've got an array of anonymous hashes. Each hash has a string for a key. Each value of this hash is an anonymous hash keyed with numerical keys. I'm trying to use Dumper to print this data structure. I have the $Data::Dumper::Sortkey variable set to this subroutine: 
sub hash_sort {
  my ($hash) = @_;
  return [
  (sort {$a <=> $b} keys %$hash)
   ];
}

The problem is that this throws errors like 'Argument "apwu749_d5" isn't numeric in sort at update_settings.pl line 87' because it's trying to sort the hash keyed with a string numerically. What's the best way to modify this subroutine so it works for all kinds of hashes?
