I think something like this might do what you want:

git for-each-ref --format='%(refname)' refs/tags | \
while read t; do
   if ! git merge-base --is-ancestor $t HEAD; then
     echo ${t#refs/tags/}
   fi
done

If you run that on the Git repository (assuming you've checked out  
master), after a while (there are a lot of tags to check) it spits out  
v1.4.4.5 (along with some complaints about *-gpg-pub tags that refer  
to blobs).

And sure enough, `git log v1.4.4.5 ^master` shows 5 commits not  
contained in master so I think it does what you want.  You'll want to  
restrict the for-each-ref output further, if possible, to make it  
quicker.
