That very well could be the problem.
jquery-1.4.4.min.js is another jQuery Library, and will render break on most installations.
Try removing jquery-1.4.4.min.js, and see if that helps the issue.
Side Note: Officially for PCI compliance you should only be running the most recent version of jQuery, including more recent then 1.10.2. (currently the most recent version is 1.11.2) running the migrate 1.2.1 provides backwards compatibility with older scripts.
