Two problems of quizzes published to HTML5 and scorm 1.2

I made a quiz slide include the sequence type question.

I published it to HTML5 and scorm 1.2 by Presenter 11.0 and upload my e-learning web server.

1. My e-learning server cannot get the score of sequence type question at any browser(IE,chrome,firefox). the other type question can get it.

2. When using safari browser of iOS, the server cannot get the score of all questions and do not called "finished" method too.

(This e-learning server can get the score from the same quiz published by Captivate.)

Is there the solutions of these problem?
