In the Rails world, there's the concept of migrations, scripts in which changes to the database are made in Ruby rather than a database-specific flavour of SQL.

It should be possible as the Task Scheduler has a scriptable [COM API][1] that can be used for interactoing with tasks.
You could therefore either create a custom task that uses COM interop to call the Task Scheduler API, or it'd probably be quicker to use an Active X Script task to do your dirty work.
