Please review http://codex.wordpress.org/Function_Reference/wp_enqueue_script and update your plugin accordingly.

Keep in mind: Offloading the default jquery and other scripts to Google is similarly disallowed for the same reasons, but also because you're introducing an unnecessary dependency on another site. If your code doesn't work with the built-in jQuery, it's most likely a noconflict issue. If you can't guess, we -really- want you to use our jquery, and if you can't, we need to know why so we can fix things for everyone.

When you've corrected your code, reply to this email with the updated code attached, or provide a link to the new code.
