Figuered it out by going to the microsoft site. It told me to.

Move individual tasks up or down in the task list

In Tasks, on the View menu, point to Arrange By, point to Current View, and then click Customize Current View.

Click Sort, click Clear All, and then click OK.

Click Group By, click Clear All, and then click OK twice.

Drag a task (task: A personal or work-related duty or errand that you want to track through completion.) up or down in the task list (task list: A list of tasks that appears in the Tasks folder and in the TaskPad in Calendar.), using the guide to position the task.

To save this order as the default, on the Actions menu, click Save Task Order.
