The same reason as above. I think it's better asking user to run --sort manually.

I think we can add a hint by checking the auto-generated header line
`# auto updated by update_mc_test_check.py UTC_ARGS: --sort`

if there is a `--sort` there but there is no `--sort` being passed by the arguments, we can shot a warning
