Denotes question regarding Magento Category Product sorting

The position of products in a category can be specified manually by dragging and dropping products into position, or by applying a predefined sort order. By default, products can be sorted by stock level, age, color, name, SKU, and price. Automatic sort overrides the current sort order, and resets any drag-and-drop positions that were set manually. The sort order of colors and the minimum stock level that can be required for products to be included in the list are set in the Visual Merchandiser configuration.

You can set up the category options separately for each store view to determine the selection of products, their relative position in the list, and the attributes that are available for category rules.
