Actually, I think what is happening is that just one record is moving to the top of the list. For example, in the records for the custom post type, I have the following first names in order of most recent first:
Regina, Anne, Lori, Laura.
If I do not do the sort in the get_posts query, they are sorted as shown above; Regina is the first record, as that is the most recent one I added.
If I do the sort in the get_posts query, Anne is moved to the top of the list and the remainder are in the order they were entered with most recent first:
Anne, Regina, Lori, Laura
