Adding tags to a Reminder

Does anyone know how to add a tag to a Reminder? I’ve got my first script doing everything i need it to do EXCEPT add a Tag to a reminder - i’d like to not have to add the reminder with scriptable and then come back thru with the native shortcuts to re-tag everything.

Looks like it might need to be a feature request for Simon. I don’t see any property or method supporting tags on Reminders listed in the documentation.
