I've fixed the sort-by flag in https://github.com/openshift/oc/pull/44 but the remaining two are coming from printer flags. I'll need to have a one more look, though.
Checked against 4.3.0-0.ci-2019-10-14-031716 and it's working as expected.
Confirmed with latest oc client, the issue has fixed: oc version: 4.3.0-201910141917.git.1.7327846.el7 `oc new-build --help` couldn't have the sort-by flag now.
