For what it's worth I have these values calculated and they are on the web site of Bob Gribus, who wanted to post them there for his readers. These are the Number of Defects (parts per million) for Various Sigma Shifts in the Process Average for Different Sigma Capability Levels, from 3 to 6. They were calculated using Excel, and Bob has included the Excel formulas as well as the calculated values. Here is the web site.

I don't think that having the two-tail values as opposed to the one-tail values is such a big deal once you get above a sigma level of 2.

P.S. Does anyone else use anything different than the term "Sigma Level"? Please e-mail me if you call it something different.
