I'd be willing to bet that a 1090T and an 1100T from the same batch stand a 90% chance of being able to hit the same clocks. The ones that are unstable at the 1100T's clocks on the stock cooler and at the stock voltage are sent to become 1090Ts or if they're really unlucky 1045Ts for OEMs.
The reason people buy the higher AMD chips is because they want to get rid of the possibility of getting a bad clocker. Intel's binning is quite a bit more meaningful. Back in the C0 and earlier Bloomfield days, you'd need an i7 940 if you wanted to be sure you were able to hit 4.0 ghz.
SandyBridge doesn't have as many models out on the market yet so there isn't as much binning right now, and when BD first comes to market there won't be much either.
The 8170Ps are going to come out in 2012 (probably Q1 or Q2) and so they'll likely be a different chip revision than the earlier 8130Ps and 8150Ps. However, when the new revision is launched the lower chips will be made using that revision once the back stock is gone.
