Maybe something like this?
foreach($list as $k => $v)
{
$p = explode('-',$v);
$new_list[$p[2]] = $v;
}
ksort($new_list);
reset($new_list);
$new_list will have the XXX number as the key of the array element and
the name of the file corresponding to the number as it's value.
If that won't work, let us know.
