Invite adding points to the wrong user on account creation

I saw this issue with the HEAD version, but I didn't see it being resolved with 1.1. I'm running Userpoints 5x-1.1 and Invite 5x-1.2. I'm sure the bug is in this section of code, but I've only been using Drupal for about a month and haven't been able to fix it on my own yet.

When a new user creates their account based on an invite, the account with uid=2 is always getting the points.

function userpoints_invite($op, $args) {
  switch($op) {
    case 'invite':
      $points = variable_get(USERPOINTS_INVITE_INVITE, 0);
      break;
    case 'escalate':
      $points = variable_get(USERPOINTS_INVITE_REGISTER, 0);
      break;
  }

  _userpoints_update_points($points, $args['inviter']->uid, $op);
}

The inviter is always getting set to uid 2 on my site, and I've tried my own fixes to get it to work properly with no luck so far. Is there a version of Invite (that doesn't involve going to the buddylist version) that would correct this or is there a snippet I could add to this function to make it work properly?
