It does not say it was "registered", it says that it was "assigned":

    11. IANA Considerations

       IANA has assigned the ACE prefix in consultation with the IESG.

This is not a pedantic difference: IANA keeps registries for things it 
has registered. This prefix was assigned by IANA as a neutral body that 
helped determine a prefix that was unlikely to have been used in public 
domain labels; you can read the mailing list for why that came about 
that way. There was no registry for prefixes because it was a one-off 
for this RFC only. That can change in the future, of course.
