I agree. No matter what the voting system, a tie will always be a
potential outcome and it simply may not be practical to repeat a
vote, especially if it was a preference voting system and people were
honest, until the tie disappears.
In this case, the only fair way, as near as I can tell, to resolve
the situation would be through a random selection.

I found this paper on the web which looked interesting, but I haven't
gone through it yet. Anyone care to comment?
