Enqueueing script works but script has no effect

I’m attempting to use this script (a Soundcloud player) on a custom taxonomy template. I’ve successfully enqueued the script in my theme’s functions file. I’ve called the test snippet as shown on the script’s homepage in my template:

<script type="text/javascript">
$(document).ready(function(){
$stratus({
auto_play: true,
download: false,
links: 'http://soundcloud.com/qotsa',
random: true
});
});
</script>

Yet it is having precisely no effect. Currently I can’t work out why. I have no errors in Firebug and everything seems to be ok.
An example of the page where this script should show is:
