Add another PHP sort function

I had this site php built by someone else and can't get into contact with them. I need another sort function added similar to one that already exists. The url is [url removed, login to view] . If you look at the with pooltable button on the left it needs to be very similar to that. Contact me and i will go over it more. I have already tryed to work on this some but i am very new to PHP.
