[VE][127] seemingly invalid error message

While using the Validator on my web site  <http://www.ahtcsonline.com>
www.ahtcsonline.com, I received an error message that I don't think is
appropriate since the element 
that they are say is missing is there.  The message says that I am missing
the ">" after the .js and before the closing "</script>.  Can someone please
explain why I am getting errors on "missing" elements when they are in fact
in my html.
 
Line 136, Column 53: required attribute "type" not specified 
<script src="http://widgets.twimg.com/j/2/widget.js"></script>

The attribute given above is required for an element that you've used, but
you have omitted it. For instance, in most HTML and XHTML document types the
"type" attribute is required on the "script" element and the "alt" attribute
is required for the "img" element. 

Typical values for type are type="text/css" for <style> and
type="text/javascript" for <script>.

Error [127]: "required attribute X not specified" 

 

Thank you for such a great tool,
