Use .val() to set the value to 2 as follows:

$(function() {
    $('.mySelect').val( 2 );
});

$(function() {
    $('.mySelect').val( 2 );
});

<script src="https://ajax.googleapis./ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select class="mySelect">
  <option value="1">Date</option>
  <option value="2">Helpfulness</option>
</select>

UPDATE

Per your updated question use localStorage or cookies to hold the selected value. When the page refreshes, check for the cookie or localStorage value and load it.

$(function() {
    $('.mySelect').on('change', function() {
        $.cookie('mySelect', this.value);
    });
    $('.mySelect').val( $.cookie('mySelect') || 1 );
});

DEMO

For most default value, it would be easy to set on html markup directly like :

<select class="mySelect">
  <option value="1" >Date</option>
  <option value="2" selected>Helpfulness</option>
</select>

Otherwise, use jQuery .prop code here :

$( function () {
   $('.mySelect option[value="2"]').prop('selected', true);
});

Set the value in val() and change() function

jQuery(window).on('load', function () {
    $('.mySelect').val(2).change();
});
