Had to rewrite it a little since I usesd strings. Final version, in case
someone else likes to use it as well:

function cmp($a, $b) {
$retval = strcmp($a['type'],$b['type']);
if ($retval === 0)
$retval = strcmp($a['filename'],$b['filename']);
return $retval;
}
usort($this->dircontents, 'cmp');

Again, thanks for the pointer!
