is there a way, from script, to move inventory from a sales order that has committed inventory (but unfulfilled), to a sales order that is backordered. Ideally, I would not "tell" it which order to take the inventory from ... I would just tell it "grab committed inventory and give it to order X" ... ?

@Boban Dragojlovic you can do that without a script by going to Transactions > Inventory > Reallocate Items. Is that what you’re looking for?

Thank you for your comment. I'm aware of that feature, but unfortunately I need it done via script, because I am building some automation ...

closest in suitescript is to change the line level commit on the lines
