Problem with Contribute URL decoding a javascript

Question

Hi,
On all pages of our website we have a Google Analytics script:
<script type="text/javascript">
     var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl" : "http://www");
     document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
But every time someone makes a change to one of the pages with Contribute, the script is automatically altered to this:
<script type="text/javascript">
     var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl" : "http://www");
     document.write(unescape("<script src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'></script>"));
</script>
The difference is that Contribute has decided to automatically URL decode the first of the two closing </script> tags, which breaks the script; it's URL encoded for a reason: so that the browser doesn't end the script prematurely on parsing the first of the </script> tags. Is there some setting within Contribute that will allow us to stop this from happening? We just want Contribute to leave the Javascript alone.
Many thanks,
Mark

I was able to solve this by including the google code in an external PHP file as well. However if my template has a repeating region in it, and my contribute user adds a region from it, it breaks the code again :/
Are there any other suggestions out there??
