MembershipTypeValues Hook loses altered minimum_fee value for any array items other than the first one at the Confirm step

http://forum.civicrm.org/index.php/topic,14275.msg62097.html#msg62097

I've confirmed this bug in 3.2 using the following simple hook invocation in a test module. Both membership types show the correctly altered fee on Main.php. And if I test by selecting the first membership type ('General') - it works all the through. However, if I select the 2nd option ('Student') - then the original fee ($50) shows on the confirm page and the membership is created w/ a $50 contribution instead of the hook specified $2.22.

=================

function dgg_civicrm_membershipTypeValues( &$form, &$membershipTypeValues ) {
for ($i=1; $i <= count($membershipTypeValues); $i++) {
if ($membershipTypeValues[$i]['name'] == 'General')

{ $membershipTypeValues[$i]['minimum_fee'] = "5.55"; }

if ($membershipTypeValues[$i]['name'] == 'Student')

{ $membershipTypeValues[$i]['minimum_fee'] = "2.22"; }

}
}
