How about "Standard" as the (currently default) forum theme name and leave "default" to the software hard coded.

Then it would show as (if I understood correctly)
* Default (Standard)
* Standard
* Web 2.0

Much easier to understand at a glance.
(and this coming from a developer who often has to fight to keep even some of the most basic custom UI choices in projects on the basis that many of my company's clients are even more completely computer illiterate o_O)

This seems like a decent compromise, not that I've been confused but I can see how it can be confusing.
