Works for me after fixing it by visiting https of the buzzword hosted script and accepting the "bad" cert. My schema agnostic settings–

<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.mi
+n.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.2/highlig
+ht.min.js"></script>
<script src="//buzzword.org.uk/2014/pm/pm2.js"></script>

Update: I included the settings because of the depth of the reply and that it's not just safe to remove the type="text/javascript" today, it's proper by HTML5 validation standards.
