1.2 beta 3 install SQL error roadblock

[cloudseat]

No matter what I do, when I attempt to update to the latest beta I get no further than step 3.
I've made numerous attempt following the wiki, the sticky, and a few other well regarded posts.
When I log into my newly updated back office it still reads Version 1.2.0.5 - 0.129s
I am able to do a clean install, and the beta seems to be working perfectly.

This is the error I'm getting:

Congratulations!
Update is finished.

Unfortunately, 4 SQL errors have occurred.
