Prestige is done in turn order, no? Starts with the holder of the Queen token and goes left. And there are no ties: if player one has 5 and player two has 5 as well, player two goes to the next lowest spot on the track.
That's from memory, but I believe I'm right.
Prestige is determined in turn order and as he said there are no ties. If your total matches someone already on the track, you have to take the next lowest unoccupied space.
Once everyone has determined their prestige, titles are chosen in order of prestige amount, starting with the player with the most prestige and ending with the player with the least.
