I don't know - but I tested with just one root.

FWIW prio 1 is the highest for filters 0 is highest for htb.
If you set 0 you end up with a really high pref - have a look with
tc -s filter ls dev ....
What prio to use depends on what you want, the 10 and 11 are meaningless
really unless you have other filters and order matters so the match all
can become match all the packets that didn't match a higher prio filter.
