Those have been the rules since the beginning of this Beta, last fall. I've been on the winning and losing ends of those tiebreakers, it's just the way it works. Don;t blame the system though, the rules have been there for everyone to read.
Every tie for 1st has been that way. One person wins, the others get 2nd. If you don't want to read the rules that's fine, but don't complain about someone making up rules as they go along. It's just not the case, and if you'd read them all along, you'd know that by now.
Best way to beat the tie-breaker? Shoot a better score. End of story.
