Dear monks,

I have a hash of hashes of hashes. The deepest hash has a key 'RANK', with values R#1, R#2, R#3 etc, depending on the key in the middle hash: 
$entry{$table}{A}{RANK} = R#3;
$entry{$table}{C}{RANK} = R#2;
$entry{$table}{B}{RANK} = R#1;

and now I'd like to populate an array with the keys of the middle hash, numerically sorted by the integers in R#1, R#2, R#3 etc, i.e.: 
@array = qw(B C A);

[download]
by sorting the %entry hash, somehow. But how? Many thanks for any hints! (Note that the A, B, C keys are just for example...)
