You should just turn off status checks for your script:

  <rm>
    <service name="foo" >
      <script name="myscript" file... >
        <!-- 1 year status check interval -->
        <action name="status" depth="*" interval="1y" />
      </script>
      ..
    </service
    ..
  </rm>

That should make things work.
