I won't expect any miracles :).
I wonder if the Apple docs actually mean it's pointless depth sorting opaque objects, something that the OSG doesn't do by default anyway - it states sorts for the opaque bin. For the transparent bin you still need to render from back to front to get the correct blending, unless the driver knows about transparent objects needing to be render back to front. As for looking for an optimization here, I really don't think it's worth your while, you are attempting premature optimization - deciding what the bottlenecks are before you've even tested it. I would recommend doing actual benchmarks on the target hardware/OS with the types of datasets you will be using and then profile it closely to establish what are the bottlenecks.
