Randomize options

Hi guys,
currently ihave option mc’s stored in an options_array and i assign text to the text field optionText sequentially by using a loop. The options text are stored in goObjMCMAInfo object.
totalChoices = goObjMCMAInfo.Quiz[0].options[0].option.length;

 
for (i = 0; i <totalChoices; i++){
      options_array*.optionText.text = goObjMCMAInfo.Quiz[0].options[0].option*._value;  
   
}

now i want the options to be jumbled up instead of appearing in a sequential order. Can somebody please help
