I agree with your analysis that sale = acceptable price discrimination, but I think there's more to it when they do a sale on release day. That's when most of the people willing to pay full price buy it! I think it's largely to get people to buy from them instead of iTunes and thus to try CloudDrive and their mp3 service. And also to price discriminate and get people who would have otherwise not bought to buy from them and try CloudDrive and their mp3 service.
