Survey plugin that ranks answers and displays results

I’m looking for a WordPress plugin that will let me run a survey where visitors can rank 10 preferences in order of “most important” to “least important.” I also need it to display the results. Something using AJAX would be perfect. The closest thing I could find is SurveyGizmo’s plugin, which allows ranking questions, but it doesn’t seem to allow me to immediately display results on my blog. Anyone know of something that does this?
