This read-only Gauge32 value reports the execution order of a record of one trigger occurrence, a specific firing of a schedule, window, or test that can spawn one or more actual jobs relative to other triggered instances. An administrator uses this to understand the sequence in which multiple triggered firings were or will be processed. For example, when an administrator is auditing which jobs actually ran after a maintenance window opened, this order value would tell the admin which of several simultaneously-queued firings ran first.
