Sorting by "relevance" is nothing else than the position of the products in the category. You can insert the newest products first in the list of products assigned to a category.

You have to assign all your level 2 products to that level 1 category as well. There's no automatic way because this should be an explicit decision of the shop owner (or the importer). Doing it that way enables you to define the order of the products in the first level too (different from the level 2 order for example).
