Some airports always deliver in priority sequence (e.g. HKG) and others are always haphazard (and the tags mean nothing). So don't fret about this, if the airline's computer system has recognized your priority status, your bag will be properly sorted. And if it has not, it doesn't matter how many priority tags an agent will put on the bag, it still won't go into the F container.
