I've tried it.
I don't see it sorting anything?
http://cegepsherbrooke.qc.ca/~languesmodernes/test/keynatsort.php

$words = preg_split('/[[:space:]]+/',$mynewstring);
foreach ($words as $word) {
   $freq[$word]++;
}

function keyNatSort($array, $saveMemory=false)
{
   if(is_array($array))
   {
       $keys = array_keys($array);
       if(natsort($keys))
       {
           $result = array();
           foreach($keys as $key)
           {
               $result[$key] = $array[$key];
               if($saveMemory)
                   unset($array[$key]);
           }

       }
       else
           $result = false;
   }
   else
       $result = null;

   return $result;
}

keyNatSort($freq);

echo "<table>\n";
foreach ($freq as $key => $val) {
#   echo "$key = $val <br />\n";
   echo "<tr><td>".str_replace("_", " ", $key)."</td><td>$val</td></tr>\n";
}
echo "</table>\n";
