Sorting response lists containing subheadings
If a response list contains subheadings it is important that you place the ordering keyword in the right place to achieve the results you require. You may find it helpful to think of the response list as having a hierarchical structure in which the ordering keyword applies only to the level at which it appears in the interview script. If the keyword appears on a subsection, it applies only to the contents of that subsection, whereas if the keyword appears at the main response-list level it applies to the subsections themselves and not to their contents.
