Why don't I see app icon on the iTunes?

I'm developing an Adobe AIR game. In the application descriptor file I added all iOS icons:

<icon>

        <image29x29>icons/ios/Icon-Small.png</image29x29>

        <image40x40>icons/ios/Icon-Small-40.png</image40x40>

        <image50x50>icons/ios/Icon-Small-50.png</image50x50>

        ...

        <image152x152>icons/ios/Icon-76@2x.png</image152x152>

        <image180x180>icons/ios/Icon-60@3x.png</image180x180>

        <image1024x1024>icons/ios/iTunesArtwork@2x.png</image1024x1024>

</icon>

When I built IPA file and drag&drop it to the iTunes app on my Mac I don't see the app icon. Why?

I open the IPA file as zip archive. It contains only Payload folder with my game (MagicKey.app). I know that there is must be iTunesArtwork file.

What should I do to fix my issue?
