Personally I'd prefer all tests to be in the test scripts. Otherwise
they clutter up the module without serving any real purpose (except
maybe as documentation).

What exactly do you mean with 'functional' tests? We certainly don't
need non-functional tests! ;) And why would additional test scripts
throw off the coverage numbers?
