It wouldn't mean nothing. The 360 being a last-gen console means various reviewers aren't going to bother reviewing it, thus failing to make a considerable Metascore. Of course 88 is higher than 86, but the 360 version has 8 reviews and the XO has 66.
What's important here is comparing the last-gen score vs the current-gen score made by the same reviewer.
