How to get publisher access to the build label?

I am trying to make a publisher that does a git tag with the current label.

I am close, but need access to the label var. What I have looks like:


<publishers>
<onsuccess>
<execute command="gittag.sh ${project.name} ${label}" />
</onsuccess>
</publishers>

And the script I wrote looks like


#!/usr/bin/env bash
echo "Creating Tag $2 in $1"
cd projects/$1
git tag $2
git push --tags

But of course, ${label} does not mean anything, so all this script does is 
create 
a label called "${label}" and push it....


If I can't get access to the label variable from inside my publisher.. 
any idea 
how to get my repo tagged and pushed out to the repo?
