I think it should be kept as it is. Winning by countout isn't the same as by pin/submission. Take the ShowMiz/Cena and Batista match on Raw. ShoMiz didn't really 'beat' Cena and Batista, since they were busy fighting each other on the ramp.
Obviously all cases are different, but I don't think retaining by DQ/countout should have the same mumber of points as retaining by pin/submission.
