BevelReflectLogo in Python script?

[racer-x]

1. I have ML Bevel Reflect 2.0 installed and it shows up in the Plug-in browser. I assume it works then? How do I test?
2. I have script-fu installed. Doesn't show up in plug-in browser. I assume it works because I can run all python scripts. How to test?
3. Tin's python-fu is installed and shows up in plug-in browser. It loads and works until error I posted.

No .scm scripts show in plugin browser.
