If I understood well, you don't need to sort nothing, you can use the keys directly: a simple hash slice can do the job:

my %h = (one=>2,three=>4,five=>6,seven=>8,nine=>0);
print "$_\n" for (@h{qw/five nine one seven three/})'

Outputs:

6
0
2
8
4

Or even easier:

my %h = (one=>2,three=>4,five=>6,seven=>8,nine=>0);
print "$_ => $h{$_}\n" for (qw/five nine one seven three/);

[download]

Outputs:

five => 6
nine => 0
one => 2
seven => 8
three => 4

Is this what you are trying to do?
