What I did was:
-a script is called to "find-cached-revision"
-you return a library path where the revision can be found or nothing to 
 look in the default library (remember that if no revision is found it 
 will create a pristine tree).

The standard script would do something like:

case $1 in
...
find-cached-revision)
        tla library-add -d ~/.arch-cache $ARCH_ARCHIVE/$ARCH_REVISION
        echo -n "~/.arch-cache" 1>&3
        break
        ;;
...
esac

You can refine the script to do what you want, without any extra params or 
overdesign, very easyly.
