Why didn't you just use this instead:

  #!/bin/sh
  exec /sbin/shutdown -P +3 "system will power off in three minutes from now" &


If power comes up before the three minutes expires all you have to
arrange to happen is the sending of:
  /sbin/shutdown -c "Power has been restored..."

  { see "man shutdown" the '-c' means cancel ... :-}

If 'shutdown -P' doesn't power off your system then you need to adjust
the shutdown subsystem.
