Read the FAQ. 5 points difference in total score on average means 1/3 stop difference. Anything lens then 5 points, the difference is lower than 1/3 stops. 1 point is irrelevant.
It's not the first time in history have you seen these differences. The Sony's 16 MP sensor is used in all these cameras (5N, K-5, K01, K30, D7000, A580, D5100) All these cameras score within 5 points of each other, meaning you won't notice any real difference in real world.
