Duplicate scripts

I found that the best way to have a fast loading responsive site is to have multiple Hype projects and stack them inline. Some of these have a second scene that is taller than the first scene, so that when returning to the first scene the top of the first scene is too high in the browser window. I thought I would create a scroller that, when clicking a return button in scene two it would scroll to the top of the scene before the transition.
But If each Hype item has the same script would this cause a conflict within the web page?
