Section 6.5.1 says:
127-255: Rejection; the node sending the DAO-ACK is unwilling to act as a parent.
It should say:
128-255: Rejection; the node sending the DAO-ACK is unwilling to act as a parent.
The status code range of "Rejection" overlaps with status code range of "Not an outright rejection".
The text in the body of the document makes it clear that the "Corrected Text" suggested here is what was intended.
