It turns out that my hosting provider was filtering for cross site scripting attacks and 
it was killing all my file uploads and file edits within the BE. Anyhow, here is how you 
would add the external reference to the javascript

page.headerData.10 = TEXT
page.headerData.10.value = <script type="text/javascript 
src="fileadmin/templates/scripts/yourscript.js"></script>
