No, the first comment is not wrong. I thought perhaps the maintenance plan was failing itself because QI was turned ON.
Further research indicates that this is not the case. The actual problem is within the maintenance plan's extended stored procedure itself. There is no setting you can use to convince the extended stored proc to use a different QI setting.

Yes. However, I don't know if the maintenance plan turns the QI option off permanently, or if the changed option only lasts during the run of the plan.
