This is the numeric sequence position of this stage within its parent FSM run's ordered list of stages. An admin uses this ordering to reconstruct the actual sequence of steps a sync run went through when the individual stage records aren't already presented in order, confirming whether the sync failed on an early or late step in the workflow. A stage with order 1 represents the first step in the sync sequence, such as local verification, while order 3 might represent the final commit step.
