I’m afraid you won’t be able to control the different elements loaded inside the comments module, since the comment form lives on WordPress.com and is inserted into your site via an iFrame.
For the same reasons, you wouldn’t be able to overwrite the style of the comment form, regardless of the specificity used in the original stylesheet.
We’re working on adding ways for site owners and third-party plugin developers to hook into the iFrame, and you can follow our progress here:

Until we make that change, I’m afraid I can only recommend that you deactivate the Comments module if you’d like to have full control over the look of the comment form on your site.

How do I disable Jetpack’s comment module from ajax loading the highlander comments default css (style.css)? I want to style the comment box from scratch without the bloat and the horrendous practice of using id specificity in the stylesheet.
