I'd probably use sheathing tape, but it's a bitch to work with. Don't use Red Green style duct tape.
(Wait!! They use insulation in Los Angeles?? R30???)
Yeah to keep us cool in the summertime. Thanks
Not clear why you'd worry about taping the facing -- you don't need a vapor barrier.

I'm still trying to understand the tape the seams of what I assume as batt you mean fibreglass batts?
Also assume the batts are faced. I understand taping rips tears or punctures in faced fibreglass......but never heard of seams being taped. But then again, I've used 8'batts that were faced-but the only 4'batts (unfaced) were used in commercial drop ceilings.
thanks.
When in doubt, call the inspector and ask.
