Updated Code mistake cuted... (my first update :) ) If you need only top values it's one more option: 

 $data{1} = {'a' => 10, 'b' => 5, 'c' => 20 };
 $data{2} = {'a' => 90, 'b' => 15, 'c' => 40 };

  @Top =
     sort { $a <=> $b }
        map {
# cut
                        values %{$data{$_}}
          } keys %data;
  @Top[0..2];

# or simplify to
  (
      sort { $a <=> $b }
        map {
# cut
                        values %{$data{$_}}
          } keys %data;
     )[0..2];
