I have been able to solve my particular problem, though not completely. I have still not identified the exact rights needed to create and run scheduled tasks, but the following seems to work:

1. Add the to the Web.config
2. Add the IUSR user (which is the user the app will run as using impersonate) to the "Backup Operators" group.

This gives the application access to the Scheduled Tasks folder so that they can create and run the task.

We had an additional issue, which was that the tasks were attempting to run as the Local System Account. Unfortunately, only administrators seem to be able to assign the Local System Account as the running user, so we needed to impersonate as an Administrator account, not as a Backup Operator in order to get our code functioning correctly.
