Trying to optimize Auto Reclaim/Heal/Assist

[MoriturusMortus]

I am trying to optimize the "Auto Reclaim/Heal/Assist". While using this lua script, builders tends to begin to support factories or buildings which are getting build, and got stuck with it, when I ran out of metal. So it would be nice if the script check if enough metal and energy is in storage and if not the builder stops supporting and begin to reclaim or begin to heal damage units. But I like to have this feature only for builders which were ordered by the specific script to support and not all other builders I own. Is there a way to track who give the last order? It would be enough to know the specific time the last order was given.
And I have some problems to figure out how the " CMD.FIGHT" command works, how is it decided what the builder do (reclaim/Assist/heal)?

I have a script that works only with certain builder . selection by name.
