It appears vBulletin has changed the location of the Facebook Like button in version 4.1.2. As a result it is likely the code changes needed will be different in 4.1.2 and beyond, I will not be able to support installs beginning with version 4.1.2 since my license stops at 4.0.8. You can try the code and report your results on 4.1.2 and beyond. The main point is the twitter code can really be placed anywhere on showthread- it's finding the ideal location that will take some trial and error:

<a href="http://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-via="YOUR_TWITTER_USERNAME" data-url="{vb:raw vboptions.bburl}/showthread.php?t={vb:raw threadid}" data-counturl="{vb:raw vboptions.bburl}/showthread.php?t={vb:raw threadid}">Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script>

After you find the best location you can worry about a conditional to only show in some forums if you want.
