wp_enqueue_script won't load remote scripts

I’ve been trying to troubleshoot an issue I’ve been having with wp_enqueue_script for over a week now. I’ve read everything I can find on wp_enqueue_script and nothing addresses the problem I’m experiencing.

Here’s the code in my functions.php:

function my_scripts() {
    wp_enqueue_script( 'jquery' );
    wp_enqueue_script( 'modernizr', 'http://cdnjs.cloudflare.com/ajax/libs/modernizr/2.0.6/modernizr.min.js', 'jquery', false );
}
add_action( 'wp_enqueue_scripts', 'my_scripts' );

The issue I’m having is that modernizr isn’t getting loaded. If I view the source that’s being generated I see this:

<script type='text/javascript' src='/ajax/libs/modernizr/2.0.6/modernizr.min.js?ver=3.5.1'></script>

Somehow the remote url is being removed. My question is why? And how do I get it to load from the remote source I’ve specified?

Thanks in advance for any help you’re able to provide.

Best,
Mac
