Brian,
Just tried the hack I had suggested on a 1.9.9 version of Moodle and it works as advertised. In the user interface this question type is called "Multiple choice", but in the php files it's referred to as LESSON_MULTICHOICE.

in file mod/lesson/view.php, simply comment out line 612:
case LESSON_MULTICHOICE :
$i = 0;
//shuffle($answers);
foreach ($answers as $answer) {...
