Say that, at any given moment during a Quidditch match, Team A has 150 points and Team B has 0 points. Then, in the next moment, Team B's Seeker has caught the Snitch. Both teams now have 150 points and, with the Snitch caught, the match is over.
Is there an immediate tie between the teams? Perhaps there is, instead, a sudden death face-off of some sort? Or does Team B win by default, and catching the Snitch counts as a tie breaker?
The last option sounds most probable to me, but I'm interested if there are any canon accounts of the above situation and how they were resolved, as I can't rememebr any mention of it in Quidditch Through the Ages or the old Quidditch videogame I used to play.
