That said, I've added tests for all (relevant) exploits on the XSS (Cross Site Scripting) Cheat Sheet website.
I don't know what tags you generate through HTML::BBCode, but you may need to override (by sub-classing) the default list if you need to add any.
Also, I think that your HTML generator would be a good match with HTML::StripScripts, because StripScripts need to receive tokens, and your module is generating tokens... the interface should be pretty easy.
If you need any help with it, drop me a /msg
