There's essentially no difference, but what MZD posted is probably better in case Wikia adds more to the header. You probably just had a delay in the script working due to caching.

I've been contacted on my message wall about this before, and here is the latest code. This will work on the new header and also changes the wordmark in Special:Chat.
