As a native English speaker I didn’t find it ambiguous. I don’t know why though. I think your confusion is because “ordered” could mean they were ordered to do something, but it could also be the past tense of them ordering someone else. However, “ordered to” would not work in the past tense so this headline must be referring to them being ordered.
