I'd like to add a way to return the status of any existing tasks instead of creating new ones

Are you not creating the tasks in the first place?

You can create a Scheduled Script Instance Search to get the tasks IDS that are not cancelled, pending, and complete.

Task ID is a column if you need the task IDs, otherwise, you can get the status as a column to and also add filters for script, etc..
