reordering issue

Hi guys

I am having in issue while am tryiing to reoder some tasks

Tasks priority
task 1 1
task 2 2
task 3 3
task 4 4

Let's say I want to reorder the priority of those tasks and need the task 3 to be on the top, So I would cut the whole row and insert it in front of task 1 but I want the priority column keep the same ranking which means from 1 to 4 in that order and not 3, 1,2,4.

How could I automate that. I dont want to just renumber the priority column.
Thanks
