If score is as important as you believe, then making anything but getting a win condition losing (the status quo) is the best option. Back when I was in the states, I never lost a match from "connection problems", so I don't think it's the server's fault. In addition, if you could intentionally play AI in pvp by purposefully losing connection, then that would be a terrible exploit, so assuming "you've lost until you've won" is better than assuming "you've won until you've lost."
