You are using Selenium RC here. I have no idea if there is a Python API to 
it or what that API looks like. The rest is just trivial code that you can 
map 1:1 to Python:

     def count_css_matches(css_locator):
         java_script_code = '''
             var cssMatches = eval_css("%s", window.document);
             cssMatches.length;''' % css_locator
         return int(selenium.getEval(java_script_code))

Although I'd simplify the JavaScript code somewhat to make it a plain 
expression.

If that's not what you want, please be more precise, or look at the CSS 
selectors in lxml that Jon Clemens pointed you to.
