Change weapon when 'x' mobs on screen!

[kroto]

Hello my fellow Xenobotters. Today I need a little hand, since I have been looking and trying to code it myself. Well, the thing I need is:

A script that changes knife to fire sword when 3 or more mobs (rotworm, carrion rotworm) on screen. Please help me, thanks.
