[fdo-internals] Sorting in SDF?

Hi Jason,

Although the SDF capabilities state that ordering is not supported, it
actually is supported by SDF Provider's SelectAggregates command.
It just isn't supported by the Select command, so there was a decision
to set the capability to say its not supported.
Also, I'm not sure if there a performance issues for large sets that
need to be sorted -- your mileage may vary.

It looks like ordering is not supported in SDF?

Any idea what it would take to add support for this?  It's pretty
important for a couple apps I'm working on where I need multi-key sorts.
