Reverting trunk back to a tag, what's the standard way?

DAH, the code I have in my project's trunk started breaking a lot of stuff.
I'm only about 12 revision off. What is the best way to tag the contents of
a tag and put it in trunk?

I have a tag called "release_1.3.1_rev796" that I want to be in trunk now. I
was thinking of deleting trunk and copying that tag to trunk, but then
technically the tag wouldn't work as it points to older version of trunk..
Should I use the svn move command? (svn move ./tags/release_1.3.1_rev796
./trunk --force)?

Thanks
