Section A.5.5.1. says:

There is the following comment:

* First, construct the chime list of tuples (p, type, edge) as
* shown below, then sort the list by edge from lowest to
* highest.

It should say:

There should be some statements to do the sorting since the comment mentions it. But there are no statements related to sorting in the following code. 

And I checked the NTP reference implementation. There is code to do the sorting at https://github.com/ntp-project/ntp/blob/71a962710bfe066f76da9679cf4cfdeffe34e95e/ntpd/ntp_proto.c#L2837

Notes:

From https://mailarchive.ietf.org/arch/msg/ntp/zJNoHvZ08SPX-3kwflMK7PIReFo/ :

"""
... correctly identifies the problem, but it doesn't provide the new
text. I'd suggest to add "sort(s.m, n);" right after the first while
loop in A.5.5.1.
