What determines the order of the friend list on the new facebook timeline?

It isn't in alphabetical order. The people at the top are my better friends, but some people up there I never speak with. It isn't random either, because every time I refresh the same people will be near the top, just in a different order

Newest friends maybe

According to Facebook:

“By default, a changing selection of all your Facebook friends always appears under the Friends heading in the left column of your profile. This selection might include friends who you interact with the most in Wall posts, comments and mutually attended events. However, Facebook does not select friends to show based on whose profiles you choose to view or who you interact with over messages and chat.”
