Okay, I get these keys from the hash:
When printed with Data Dumper they look like this:

$VAR1 = [
          '-12'
        ];
$VAR1 = [
          '7'
        ];
$VAR1 = [
          '26'
        ];
$VAR1 = [
          '-123'
        ];
$VAR1 = [
          '7'
        ];
$VAR1 = [
          '39'
        ];
$VAR1 = [
          '30'
        ];
$VAR1 = [
          '32'
        ];
$VAR1 = [
          '-504'
        ];
$VAR1 = [
          '-12'
        ];
$VAR1 = [
          '150'
        ];

They are always in that order, even when I sort them, reverse them ...

I think this is what you want
