The ideal way for any player to find a clan that's right for them is to check them out for themselves. They can guest in chat (or pm a rank) and ask questions for answers about things that they find important.
Also, rating a clan is subjective. What one person finds appealing, another won't like at all. And what makes a good clan is not limited to citadel size, ranking system or how many people are in the chat at any given time. Of course, these can all be a factor but are weighted differently from one individual to another.
Trying to promote Clan Score and not being able to answer questions ('not my department') doesn't build much credibility for your venture either.
For these reasons, I'll pass.
