You have to list schools that she is considering to have an idea. Most state schools with merit aid are simply going to take the highest score. A 29 may already qualify for max merit aid at some schools so nothing more would be needed. You have to research individual schools and I would start with your state flagship.
Upper tier schools that may look at a lower score negatively but require all scores need a score about 29 anyway so she would need to take it again.
