Taskbar Shuffle is a simple utility which allows you to do just that - shuffle your taskbar. Quite often when developing using a lot of open windows, I'll get used to windows being in the taskbar in a certain order. Occasionally that order can get interrupted, due to crashes or restarts, which is where Taskbar Shuffle comes in. I'd actually found a way to workaround it using Ultramon and multiple monitors, but the shuffle utility is a lot more convenient, as well as not requiring a second monitor.
