RenderSection can only exist in Layout files (i.e. master pages)… its purpose is to allow the pages you can request directly to target various sections of a Layout (layout being a file common to all pages which choose to use it) and supply content for these different sections.
If you want to separate this section out as something which is resuable on many pages you should put it in a partial and replace the rendersection call to something like
@Html.Partial("Scripts")
