OK now I get it, AFTER I replied.

Preserve Numbers *might* be PDF/X-3 but you can't have both untagged  
RGB and untagged CMYK at the same time like you can regular PDF.  
Everything not in the output intent space already would need to be  
tagged.

Normalize to CMYK *might* be PDF/X-1a if you conform to the PDF/X-1a  
format including setting an output intent and stripping all other  
profiles.

I like normalizing to sRGB rather than to the current display  
profile. Either could be PDF/X-3 (output intent is sRGB and all  
content is literally untagged which means the output intent is the  
assumed source profile for everything).
