A smart way to resolve this is to use a server-side 301 redirect to the actual page. I'm having a similar problem with a few pages with the url rewriting scheme I have going which allowed spaces to replace -'s. I've fixed that with PHP by taking the page url parameters, comparing them with the current requested URI and redirecting it they don't match.
I somehow don't think noindex works as well as some people suggest. 301s have had the best outcome in my experience.
