Hi.
It sounds like you may really want to have two ordering events on the same slide.
I made a draft of what might work for you. It is an ordering quiz slide that also contains a drag and drop interaction on it.
I shrunk the size of the ordering question to allow room for a drag and drop interaction. The drag and drop allows the learner to get instant feedback by changing the state of a Feedback image. Triggers simply tell Storyline to change the state of the Feedback image depending on where the learner drops the text. This gives the learner instant feedback, but the original ordering question that was built in with the slide will not give feedback until the user clicks submit and either the correct or incorrect layer is shown.
It sounds like you are using actions and events. You could obviously create the built-in ordering to deal with the events and have the actions give instant feedback with the drag-and-drop if you wanted the user to approach them in the order of actions first and then events. My example that is attached is probably doing it in reverse order of what you want.
Maybe this will be helpful to you.
