My Guess is that you may have to add this tag to your skins layout.master file.
Open both the page.html and the layout.master and check to see if layout.master has the tag in the same place as the page.html. It may not be there. If not add it.
I just did an Artisteer 3.0 skin about 2 weeks ago and I had to add 4 artisteer tags to my layout.master to get it to work. 4 out of 5 skins I do in Artisteer need no changes to work in mojoPortal. It;s that other 1 out of 5 where you need to get out your file compare tool.
