i thinking create custom option product , set short_order of value. if right use code.

go app/code/core/mage/catalog/model/product/option.php

there function getproductoptioncollection line no:- 373 . comment out code of ->setorder('title', 'asc'); , add " ; " after ->setorder('sort_order', 'asc')

public function getproductoptioncollection(mage_catalog_model_product $product) {     $collection = $this->getcollection()         ->addfieldtofilter('product_id', $product->getid())         ->addtitletoresult($product->getstoreid())         ->addpricetoresult($product->getstoreid())         ->setorder('sort_order', 'asc');         //->setorder('title', 'asc');      if ($this->getaddrequiredfilter()) {         $collection->addrequiredfilter($this->getaddrequiredfiltervalue());     }      $collection->addvaluestoresult($product->getstoreid());     return $collection; }
