script tag not working

I have the following script from my Twitter account

Tweets by @fmsReliability
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>

and I switch to Text on the page editor, paste the above, and only get the link in the first part

No listing of tweets.

From what I understand <script> should work. I'm also not having success with a script from RebelMouse - nothing.

the twitter page is on my site using wp3.5 and Thesis1.85
