It's because of the "upcoming" status on Air Screech, like we were talking about above. Even though it was released in Oct 2012 in Hong Kong, it still has the "upcoming" status associated with it and, like shmax said, the system will sort it like that.
I guess I would be in the camp of "it was released somewhere, go with that date when sorting", but then I thought about all the U.S. stuff that Malaysia, Singapore, etc. gets first, which could affect sorting when looking at U.S. portions of the database.
As far as released vs. upcoming...if something is supplied a date, any date, I'm assuming that it instantly gets the "released" treatment, even if the date is in the future. The only time you'll see "upcoming" is when there is no date supplied.
I guess it would be possible to use "upcoming" for both when a future date is supplied or when it is unknown, but I have no idea how much work would be involved, though.
