Just tried it, worked well. On Solaris 2.7 with mergesort I get from

$a = array("socket", "370", "99", "3d");
sort($a);
var_dump($a);

array(4) {
  [0]=>
  string(2) "99"
  [1]=>
  string(3) "370"
  [2]=>
  string(2) "3d"
  [3]=>
  string(6) "socket"
}

So it works. On systems were qsort() works, changing to mergeseort()
will change the order in some situations (I think), but people shouldn't
rely on that order anyway.
