Actually Offensive/Defensive Power Rating IIRC. The OPR by itself (for a single team) does not give you a ranking, but rather a rating of how much it theoretically contributes to a team.

OPR should never be used as the only scouting mechanism.

I think it should still be accurate. If your robot contributes points on average to the alliance it is on (whether by feeding balls to the next zone, scoring balls, hanging each time, or even just having a good strategy), then your OPR will be higher. Since the scores are linear and human players have very little to do with it, it should be more "accurate" than 2009.
I agree that OPR shouldn't be used as the only scouting mechanism. However, I still think that OPR's accuracy is dependent on how often you see the shutout collusion (or an alliance shutting itself out on purpose), since that seems to have been the hot topic in strategy discussion. Every time somebody does one of these, it will skew the value of OPR for all six teams (too low on one side, too high on the other). As long as both teams are actually attempting to win, however, I agree that you probably won't see much scoring for the other alliance.
