Agree with iterateCGI... The score is not that important to sales. When I purchase models, I look at the model for general quality, the polygon and vertex count to determine if the model is too big for my intended use, the wireframe image (again to look at general quality of the model). I do think the wireframe image is important - many professionals purchasing models need quads, not triangles, and they need to learn whether the model has good geometry in all the right places. As an occassional purchaser of other people's models, I also look for some indication the model is well UV mapped, and the more comprehensive the written description is, the better. If the textures applied are relevant to my intended use, I look to see if these are well-described also.
I'm guessing that most potential purchasers do the same. A hundred different images are only useful if the model is very complicated and many different kinds of details should be shown. But five different views of an apple is a waste of time.
The matter of lots of tags might be a little bit debateable. Most purchasers are going to search on about three search words/keys. You need at least three tags to position the model in most people's search paths, and then a couple that might help in differentiating your model from those of others in the general category. But after that, I suspect lots of tags are of marginal value.
