My assumption is that CF has something like a SVM that it's feeding a bunch of datapoints into for bot detection. Go over some threshold and you end up in the CAPTCHA jail. I'm certain the User-Agent is part of it. I know that for certain because a very reliable way I can trigger the CF stuff is this plugin with the wrong browser selected [1].
