why did you choose Teamviewer 12?

Probably because it was the most recent Teamviewer version at the time of writing this script. I just didn't bother to update it here afterwards. You can find the most recent version on its official page: Teamviewer Download

Thanks for this. I'm trying out Elementary OS for a bit.
