Question:
The following command line causes my script to throw due to missing arguments. The problem only happens when the -WebServerList parameter contains parentheses to denote an array.
This is launched by TeamCity, which I assume is making a simple Windows shell command and so its possible that the () are being interpreted by the shell/Windows.

However, I’ve tried DOS escaping e.g. ^( ... ^) and that doesn’t help. Invoking PowerShell scripts from Windows has always been hard work, afterall who’d wanna do a crazy thing like that right?!
In the mean time, I’m going to change my script to access a CSV in a single string and split it manually, so I can go home, but it’d be nice to know if there’s a proper way to handle this.
Answer:
It seems like the issue is that array configuration cannot be correctly defined by the OS. You can achive something similar to what you want by using -Command instead of -File:

Cheers, Chris.
I took the liberty of editing your answer to demo the results, and prove it works.
