I have to say that you can't assess programmers by the coding style only.
People could have problems with software design and understanding of business logic even if they learned the style guides.
So the score is assigned based on the style and understanding of the language features only,
which is worth only for hiring people for translation of the code from other languages.
Also, I'd shuffle the links, so that the best code quality is found somewhere in the middle.
