Thanks, this was the key. Sorting by date doesn't seem to be possible without setting "LC_ALL=C". The sticking point seems to be the minute field.
Small correction, setting LC_ALL is not always required in order to use sort's "-M" with syslog datestamps, but it is when LANG is both defined and defined as some value other than C. 4.0's /etc/environment is where this was being set, to UTF-8. Not sure why "sort -M" would differ between C and UTF8 but if there is no reason this but bug report can be re-filed with GNU.
