hi.... can any one explain me what's happening in the following cold... 
use Tie::Hash::Sorted;

 my %ages = (
     'John'   => 33,
     'Jacob'  => 29,
     'Jingle' => 15,
     'Heimer' => 48,
     'Smitz'  => 12,
 );

 my $sort_by_numeric_value = sub {
     my $hash = shift;
     [ sort {$hash->{$b} <=> $hash->{$a}} keys %$hash ];
 };

 tie my %sorted_ages, 'Tie::Hash::Sorted',
     'Hash'         => \ %ages,
     'Sort_Routine' => $sort_by_numeric_value;

 for my $name ( keys %sorted_ages ) {
     print "$name is $sorted_ages{$name} years old.\n";
 }
