This exists in more than one location, on the front page you will find the code for the top seller, on the templates
like view items pages you will find it on the viewitem templates code like this:
< a href="< !--SellerFeedbackLink-- > " > ( < ! --SellerScore-- > < ! --SellerVoters-- >< / a >
you can also search the language for the above text search for SellerScore for example using the search option in the language module.
