Section 8.4 says:

(Paragraph 2):  if supported, the 5.7.1 enhanced status code

       550 5.7.1 SPF MAIL FROM check failed:
       550 5.7.1 The domain example.com explains:
       550 5.7.1 Please see http://www.example.com/mailpolicy.html

It should say:

if supported, the 5.7.7 enhanced status code

       550 5.7.7 SPF MAIL FROM check failed:
       550 5.7.7 The domain example.com explains:
       550 5.7.7 Please see http://www.example.com/mailpolicy.html


5.7.1 generally refers to messages refused due to content or LOCAL policies.
5.7.7 refers to messages where there is an integrity problem.

5.7.7 is a better description for rejecting an unauthorized message due to the application of automatic checking criterion set by remote validation.

The author of this errata notes that the IANA is showing a pending addition to the enhanced codes to add SPF-specific error code 5.7.23 (in lieu of 5.7.1 or 5.7.7), but currently sees no valid RFC proposing it. The draft is located at: http://tools.ietf.org/html/draft-ietf-appsawg-email-auth-codes-07
The code used was the clear choice of the working group, and can't be changed through the errata system.
