Feel free to submit a PR. Also, I would be surprised if there weren't a few more leaks of this nature. They're probably small enough that most games won't ever notice during even a long runtime, but always nice to fix even minor/infrequent leaks.
(also, there's a macro used for this)

ScrollView::~ScrollView() { 
    CC_SAFE_RELEASE(_animatedScrollAction);
}
