There was a rumor back in college when we cared about social clout that the handful of people you see on the Friends list on your profile are the people who most recently/frequently check your profile (i.e., viewing someone's profile is already an interaction metric for FB). This trained me to not visit other people's profiles. To this day (when that list is just "most recent friends added"), I visit profiles very rarely and only if there is really something I want to check.
It's not so baseless either. Of course this might be some bias or another working but there was a time I fell behind certain commitments to a Dev Group I was helping organize and poof, the friends list on my profile started to show my co-organizers. Felt like they were checking on me, on why I'm behind my stuff, why I was taking time to echo replies. I was just busy; sorry it happens. :)

Stop, or I'm going to have to kick you in the bass.

If you both have the Facebook app with location tracking on, Facebook does know about this, which is why you sometimes get friend suggestions for people after you spent time near them (eg you were at the same party or they visited your house to do cleaning or plumbing), even if you have no mutual friends.
Anyway, Facebook re-ordered them. And so I followed up with a post asking why that happens. It turns out some of my friends saw other orders, some got the order I intended. Intriguing.
Fortunately one of the scientists thought of a perfectly rational and testable explanation, she tested it, and demonstrated it's apparently right.
Facebook has some internal "How much you interact with this person" metric and it's using that for sorting. It has no way to know your relationship to Sarah and Dave in the real world, it's just putting Dave first (for example) because the two of you exchanged a dozen terrible fish puns last week, a measurable Facebook interaction, whereas that walk out by the lake with Sarah when her mother died isn't on Facebook.
