I haven't yet figured out what's going on here.... whether it's a bug  
in the OpenType tables in the font, or a bug -- or unimplemented  
feature :) -- in xetex's OT support.

Interestingly, you do get the oldstyle numerals if you use the c2sc  
feature. (But that also affects uppercase letters, so it's not useful  
as a general workaround!) It may be that Adobe is using different  
table structures than in past fonts, and the ICU library isn't  
handling them properly.
