I wrote a very similar solution, except for the iterations in the @data-building block. 
while   ( my ($section,$v1) = each %$hash ) {
  while ( my ($item,$count) = each %$v1   ) {
    push @data, [$count, $section, $item];
  }
}

This is not a knee-jerk premature optimization; it is how I think of the loop. I believe that, as an idiom, while/each should be favored over foreach/keys when the key and value are both needed but the order of access does not matter.
And I am evangelizing. :)
