Apparently the decision has been made already but if not, here's another vote for the order they were originally released in, for the (story-related) reason mentioned. I would advise against playing them in the chronological order until you're familiar with the series, as there's quite a few things you could totally miss if you play them in that order. For example, you might want to be familiar with Raiden before playing MGS3.
