Sometimes you can't start a task before completing another one. It would be helpful to create such dependencies for your tasks. You could use this in conjunction with durations and due dates to get clear estimates how long certain tasks will take and if the due dates are realistic.
If you are using the tasks for some automatic scheduling you could apply the same priority to dependent tasks to sort the tasks in the order you have to complete them.
