There already exists some mechanisms for EXP setting.  Although there is
probably area for improvment.  I should not that I have not tested EXP
setting for about a year and a significant amount of development has
occureded since then, so you may run into some bugs, if so let me know and
I'll try and produce fixes.

A quick overview of what you will need to setup:
-bind a IPv4 route to a LSP
-use iptables to identify and mark packets
-use the markings to set EXP values (or choose differnt LSPs)
-use EXP value to determin queuing priority
