@dcandmc is correct: Merit based aid is exactly that: Based on merit. There would be no way for the scholarship to know whether the student is the beneficiary of a 529 plan or not, so it cannot have any impact on the award.
Any scholarships that take financial resources into account are need-based, or merit-based with a needs-based component.
