I've just started working on figuring this one out myself. (We have a 24-question standard evaluation we need all students to complete in every class.) I don't have an answer but I can tell you what I've discovered so far in my own hunt.
You might want to check out the questionnaire module or the feedback module. And you might want to check out the questionnaire and feedback module forum discussing these both.
From my experience, the questionnaire module implements the scale as scale-rate question, while the feedback module which is standard with moodle installation, only disabled by default, implements the scale using multiple choice (rated) question type. Not sure of other reporting needs though.
I wonder of anyone has managed to find out how a teacher is able to edit responses from each student. Consider the situation where the feedback is more of an appraisal of the student
