Well... without knowing much about your application a simple way to make it work would be to create a file that lists all the scripts that should run in which order, have each one open it, find itself in the list and run the successive one. This lets you make changes easily without totally revamping your system.

That being said, sounds like you should totally revamp your system. :) I'm not sure what your doing but a bunch of successive redirects is seldom a pretty thing.
