I'd say that displaying the rows in alternating colors is a function of the presentation. But what order the rows are given is business logic, and should be part of the business API. Ordering rows one way or another is something that your application does -- it reports by the last name, or invoice date, et cetera. And these are things that should be expressed in the queries and maybe optimized by the DBA. The real test case is this: OK, we're not using browsers any more.
