             Scripts are screen plays which are a sequence of activities or instruction that is interpreted or is carried forwards to perform a particular task. It is like a drama where the events occurs in a sequential manner.

              In the context, the three year old old little Alexander uses scripts to describes the activities that occurs in a restaurants in a sequence. These activities are, people go into the restaurant, they sit down, they get food and then eat and then finally pay. So this activities happens in a sequential order.
