You answered it yourself.  If IE is misreporting it, there is nothing we can do
about it since we honor what the browser tells us.  So if it says it is an
application/octet-stream, and MIME magic is enabled, we do a MIME magic scan. 
It seems reasonable that MIME magic might identify the file as text/plain, so
there is technically nothing wrong.

If you want to generate an improved MIME magic database system, that identifies
the file correctly, that would be great.  But (at least with our PHP coded
version of MIME magic) there are 5 signtures for msword (it's actually MIME
type text/vnd.ms-word) so if it is not recognzing it as a word file, it seems
likely that it really doesn't _look_ like a word file at all so improved MIME
magic detection is not going to help out any.
