Price scope should be store level instead of website level

[afroz92]

Till price can be assigned per website level but if we want to assign prices of products store wise we can't

Price scope is limited to global or website on purpose. The reason is that cart is shared on website level and below. If there would be possibility for different price on store view level, you could add product X with price A from one store and price B from another store leading to confusion/calculation issues. There are currently no plans to address this limitation. If needed in a specific case, probably can be done as a custom extension.
