I don't have time to check the script (I'm at work now, but I will check it tonight), but what's your problem?? You never told us. One tip, remove all isolated parameters, it's not working and they can cause very strange results. Second tip, the tbf qdiscs are useless. You are already limiting the speed in the class. If you want the classes to be able to share the non-used bandwidth, you have to remove the bounded option.
