According to Piaget's theory, children in the concrete operational stage (ages 7-11) can think logically and understand principles of conservation, classification, and seriation. Organizing blocks according to size is an example of seriation, which involves arranging items in a particular order based on a specific dimension (in this case, size). Therefore, the child in the scenario has most likely reached the concrete operational stage of development.
