Update
I completely re-wrote the test suite. You can check a live example here where results are compared with Sizzle selector engine against the common W3C page.After this Ajaxian post and some opinion exchange in its comments, I decided to extract the css2xpath function I used inside experiments in vice-versa project, creating a separated project specific for this purpose that some how could be interesting or useful.
Bugs, problems, questions, and helps are more than welcome, so far I focused my attention to SlickSpeed test selectors and nothing else but at least for that it seems to be stable and reliable.
