Ratings in the apple app store are somewhat of a guarded secret but here is short summary from a very good article about how they come up with the ranking.

While neither Apple nor Google have revealed specifics about how they calculate search rankings, it is generally accepted that both app store algorithms factor in:

Average app store rating
Rating/review volume
Download and install counts
Uninstalls (what retention and churn look like for the app)
App usage statistics (how engaged an app's users are and how frequently they launch the app)
Growth trends weighted toward recency (how daily download counts changed over time and how today's ratings compare to last week's)
Keyword density of the app's landing page (Ian did a great job covering this factor in a previous Moz post)
