You probably don't need the -T arg for a local access.

Nothing wrong: what you are seeing in varnishadm's interactive shell
is the response status from varnish (see man varnish-cli) but when you
use varnishadm as a scripting command, only the actual output is
shown.

Instead of relying on the status code of the varnish-cli command, use
the exit status of the varnishadm command.

if ! varnishadm [...]
then
    echo "varnishadm just failed" >&2
    exit 42
fi
