title: magento programatically update sort_order on option dropdown labels
body: <p>There is info on the web about how to update attribute option labels 
  (e.g. <a href="http://www.webspeaks.in/2012/05/addupdate-attribute-option-values.html" rel="nofollow">http://www.webspeaks.in/2012/05/addupdate-attribute-option-values.html</a>) but how do I only update the sort order? </p>
  
  <p>The reason I wanted to do this was that I wanted to sort manufacturer by product view count. So the manufacturers with the most global views are sorted to the top. </p>
