Thanks for your response, however we have tried this fix and it still does not update. You can see it live on this page we have specifically for testing:
https://secure3.convio.net/wcs/site/Advocacy?cmd=display&page=UserAction&id=400
This is the code for the tweet button on that page:
Tweet
Clicking the number opens the search for the longform URL, but returns no matches (that actually link to the page). Searching for the bit.ly link does return some tweets though. Here are screenshots:

Any further advice is appreciated!
