in reply to sorting tree with folders on top

I somehow miss in your code a test whether a path represents a directory or a plain file (or a symlink to a directory or to a file etc.).

    hash key 'file' represents files. folders do not have this key. that's why: 
                    if ($$a{'file'} && !$$b{'file'}) {
                        return 1;
                } elsif (!$$a{'file'} && $$b{'file'}) {
                        return -1;
                }
