Using usort() with a callback which calls filemtime()...

This is untested, but I believe it will set you on the correct path...

// First define a comparison function to be used as a callback
function filetime_callback($a, $b)
{
  if (filemtime($a) === filemtime($b)) return 0;
  return filemtime($a) < filemtime($b) ? -1 : 1; 
}

// Then sort with usort()
usort($files, "filetime_callback");

This should sort them oldest-first. If you want them newest-first, change < to > in the callback return ternary operation.
