Verifies both the order in the DOM and in the 'weight' form elements.

Parameters

$choices: An array containing poll choices, as generated by PollTestCase::_generateChoices().

$index: (optional) The amount/number of already submitted poll choices. Defaults to 0.

$preview: (optional) Whether to also check the poll preview.
