[MEL / Python] Sort meshes by TRI count script

HomeGrownHeroz

I'm currently optimising some very tri heavy meshes and wondered if something that can be scripted to sort a bunch of selected meshes based on their tri count. I have found this script that sounds like its the exact sort of thing I need but it doesnt seem to work.

Can anyone suggest either a fix or assist with writing one. My scripting knowledge is still rather limited.

Thanks
