In current implementation, the order of Tick on each vsync  is indefinite. I think root refresh driver should tick after all other refresh drivers ticked because the root refresh driver does DO a paint.  http://hg.mozilla.org/mozilla-central/file/5fe9ed3edd68/layout/base/nsRefreshDriver.cpp#l182
The order has been fixed in bug 1210261.
