In a way this will be taken care of by the review process. All apps can be reviewed by anyone who purchases them, and the aggregate rating gets displayed in the app store. The lower your rating gets, the lower you'll show up in searches. It's a way of crowd sourcing the review process. I know that at my wife's company (which makes iPhone games) they are very paranoid about bad reviews. Getting good reviews and getting featured seem to be the keys to success on the App Store. Of course, some people will lose some money in this process, but that could be considered a cost of the system which will average across the users willing to experiment with un-reviewed apps.
