Last time I tested this, upsdrvctl was correclty called at OS shutdown time. Maybe a regression or an issue with Win7. I will a have to investigate.

Anyway it is what upsdrvctl do ! When the NUT Windows service is notified to shutdown the OS, it kills all drivers first, then it calls upsdrvctl to send the UPS shutdown command to all UPS THEN call the OS shutdown command. As you say it is not ideal especially for UPS whose shutdown timer can not be set, but for now it is how it works.
If anybody on the list is able to give us a better solution, he is welcome.
