Noscript version of tags all contain tile=1

Following on from the issues raised in http://drupal.org/node/1249646
This patch must be applied after http://drupal.org/files/issues/dart-tax_0.patch

The javascript tags are fine thanks to the dynamic tile values using JS evaluation. However the tile values on noscript tags are all set to 1.

dart_tag_prepare_noscript is incorrectly assuming that $special_key_vals is an associative array but is actually in the format below.

array
  0 => 
    array
      'key' => string 'tile' (length=4)
      'val' => string 'tile++' (length=6)
      'eval' => boolean true
  1 => 
    array
      'key' => string 'ord' (length=3)
      'val' => string 'ord' (length=3)
      'eval' => boolean true

Therefore the check before incrementing $tile is not firing because $special_key_vals['tile'] is never set.
isset($special_key_vals['tile'])

The tile value should only be incremented after it is put into the tag as the first call fetches it from the initial value variable.

If the tile or ord values are not set to eval and contain a value this must be used rather than the automatic value.
