Hi,

I use sort -Vr to sort version numbers. I noticed this discrepancy on
the latest kernel version from Centos 7.8.

command to get output:
# ls -t /boot/vmlinuz-* | sed "s/\/boot\/vmlinuz-//g" | grep -v rescue
| sort -Vr
3.10.0-1127.el7.x86_64
3.10.0-1127.8.2.el7.x86_64
3.10.0-1062.18.1.el7.x86_64

I'd expect the middle value to be the highest version number. Is this
by design or a bug? If it is a bug please let me know if I must log it
somewhere.

Version details:
# sort --version
