Using AAT seems to work.

As a side note, \fontspec[Letters=SmallCaps]{Minion Pro} produces
oldstyle figures. The same is true for Adobe Garamond Pro and Warnock
Pro. However, Arno Pro gives lining figures instead, and only gives
oldstyle figures when explicitly asked. Since Arno Pro is a rather new
font, perhaps Adobe is moving towards making oldstyle figure and
smallcaps independent. IIRC, their T1 fonts had these forms together
in various expert fonts.

I will download 0.997 and give it a try. I'll report back on the
results later. Artemio pointed out his success with it, so this
problem may be fixed in 0.997.
