Maybe you would like this solution:

use strict;
use warnings;

my @arr = (
  { 'path' => '/c/', dir => '/' },
  { 'path' => '/c/a1.mp3', 'file' => 1, 'dir' => '/c' },
  { 'path' => '/c/a2.mp3', 'file' => 1, 'dir' => '/c' },
  { 'path' => '/c/bb/aa1.mp3', 'file' => 1, 'dir' => '/c/bb' },
  { 'path' => '/c/bb/aa2.mp3', 'file' => 1, 'dir' => '/c/bb' },
  { 'path' => '/c/bb/', 'dir' => '/c' },
  { 'path' => '/c/cc/', 'dir' => '/c' },
  { 'path' => '/c/aa/', 'dir' => '/c' }
);

@arr = sort sort_files @arr;
foreach (@arr) {
        my %h = %{$_};
        print $h{'path'}."\n";
}

# putting the folders on the top works, but... see output
sub sort_files {
    my $apath = $$a{path};
    my $bpath = $$b{path};

    $apath =~ s/([^\/]*\/)/\x00$1/g;
    $bpath =~ s/([^\/]*\/)/\x00$1/g;

    $apath cmp $bpath;
}

If performance is an issue, you could pre-process your array to include the modified path strings so that you only have to calculate them once.
