Section 4.1.3 says:

The version number is in the most significant 4 bits of the time
stamp (bits 4 through 7 of the time_hi_and_version field).

It should say:

The version number is in the most significant 4 bits of the time
stamp (bits 12 through 15 of the time_hi_and_version field).

Notes:

time_hi_and_version is defined as 16 bit field.

--- VERIFIER NOTES ---
This change does make the text in Section 4.1.3 consistent with the sixth
bullet in Section 4.2.2. But the issue goes well beyond that: there is a real
problem with the bit numbering throughout the RFC. Please see erratum
3546 for more details.
