Running command before suspend

I've found several posts (e.g., How do I run commands on suspend/return from suspend?, How to run a script before suspend?, Script not running on resume/wakeup in Ubuntu) that describe adding a script in /etc/pm/sleep.d or /usr/lib/pm-utils/sleep.d to execute commands at suspend/resume. However, I haven't been able to get this to work; the script seems to never execute despite having rx permissions for root. I went all the way back to simply having the script execute an echo that outputs to a file just to confirm and that nothing happens. (See script at bottom.)

What I want to accomplish is to have the suspend execute a script that runs rtcwake to implement a wake-up in the early morning for a maintenance script to run. I cannot just execute the maintenance script from cron since the system is suspended. So, I need to resume the system at a specific time in advance and then allow the job to execute.

#!/bin/bash/
case "${1}" in
  suspend)
    #suspend_actions
    echo "suspend" >> text.out
    ;;
  resume)
    #resume_actions
    echo "resume" >> text.out
    ;;
