Using Google Apps Script to set the correct answer in a Google Forms (that has been defined as a quiz)

Question

I am trying to use Google Apps Script to set the correct answer in a Google Forms (that has been defined as a quiz)

The actual Google Form can be defined using code such as

var form = FormApp.create('New Form');
var item = form.addCheckboxItem();
item.setTitle('What condiments would you like on your hot dog?');
item.setChoices([
        item.createChoice('Ketchup'),
        item.createChoice('Mustard'),
        item.createChoice('Relish')
    ]);

(Taken from https://developers.google.com/apps-script/reference/forms/)

Is there any way in code to define what actually the right answer is and to assign it points?

I know this can be done manually...

UPDATE: On April 2017 Google announced that now it's possible to create Google Forms quizzes programmatically.

At this time there isn't a method to set the correct answer. Please star the issue 6143: Create Quiz Form via API
