Running an Exec resource *before* deleting a File resource

I have a class that is adding a (rhel6) 'upstart' configuration in /etc/init. When Puppet creates the configuration file, I have to execute "initctl start <service>" based on the service name that I'm adding. The problem that I'm having is that I need an exec to run before I remove the file so that I shut down the service before the file gets removed. If I don't shut down the service, then 'initctl' complains that the service isn't there.

Now, "service" isn't in the true sense of a Puppet service. It's more of a 'reload' or "telinit q' (for SysV). Here's what I have:

case $enabled {
  true: {
    # Create the upstart file then start the 'service'.
    $file_ensure = file
    $cmd_refresh_init = "start"
    File[$iucvtty_file] ~> Exec[$refresh_init_exec]
  }

  false: {
    # Stop the upstart 'service' then delete the file.
    $file_ensure = absent
    $cmd_refresh_init = "stop"
    Exec[$refresh_init_exec] -> File[$iucvtty_file]
  }
} # case

file {$iucvtty_file:
  ensure  => $file_ensure,
  content => template("${name}/${template_file}"),
}

exec {$refresh_init_exec:
  command     => $cmd_refresh_init,
  refreshonly => true,
  logoutput   => true,
}

When $enabled = true everything works just fine. When $enabled = false, the exec never runs yet the configuration file gets removed. I would have thought that with the following chain:

      Exec[$refresh_init_exec] -> File[$iucvtty_file]

the resource ordering would have been satisfied. Unfortunately even when I remove "refreshonly" the exec still doesn't run.

Is there any way (cleanly) to get this exec to run BEFORE the File resource gets removed?
