Facebook: Sort people by number of mutual friends

The Facebook's Find-Friends page lists people, whom Facebook thinks we may know. There are some ways to filter people by hometown or college (and etc...), but it lacks the simple ability to sort people by the number of mutual friends. Using Firefox and Greasemonkey add-on and the following script it can be done easily.
Add new user script in the Greasemonkey:

Add new user script.

Fill up the following information:

Fill-up.

Then copy the following script and past it to the newly opened sortby.user.js file and save it.

In the Facebook's Find Friends page now you can see a button near the hometown filter.
Click it and it will sort people by number of mutual friends.

That's all.
