It sounds like something has changed about the construction of the  
OpenType tables, and the layout library used in XeTeX isn't handling  
them properly.

A possible workaround to try, as you're using a Mac: it *might* help  
to load them with the [Renderer=AAT] option (in fontspec). That will  
use the Mac's ATSUI system for text layout instead of ICU.

If someone out there has the latest versions of these fonts, and also  
has a recent XeTeX 0.997 build, I'd be interested to know whether the  
+onum feature works there. (I only have the older versions of these  
fonts.)
