I can't speak for any other outlet, but those were two reviews by two different reviewers. They didn't come at the games with the same experiences, same personal likes and dislikes, same eye for judging a game's elements, same hopes for what the game might do right.
A score, if it is anything, is one person's judgement of a game given their experience with that game, and relative to that game. I gave the original Persona 3 a 9.5 (if I remember correctly), and I gave The Last of Us a 9.5. That doesn't mean they're on the exact same level of quality, because that's an utterly impossible comparison to make. That means, when looking at each game as an individual experience, if 0 is the worst judgement I can pass, 5.0 is average, and 10 is excellent, each accomplished what they set out to accomplish enough, and engrossed me into their worlds enough, that I thought the experience was worth that score.
I think it's impossible to have any scoring system where you can directly compare the scores for two different things, because there's so many variables in what each game is about and what it's trying to do.
Two different reviewers. Reviewers aren't robots who all come at reviewing a game from the exact same perspective.
