I have 12 transactions from 6/7/2012 that are still sitting unconfirmed in my wallet. The transaction IDs are not found on blockexplorer or blockchain.info, and the transaction ID on the payment sitting in my wallet does not match the transaction ID of the payment on Satoshidice.
Every one of your "MY SEND" payments does show in blockchain.info. Each then shows in SatoshiDICE as CONFIRMED as well (meaning the payout has confirmed).
So SatoshiDICE looks to have properly received, and paid out to the origin address on each of those.
Now why you wouldn't see those as confirmed in your client, I have no idea.
Are you absolutely sure you have the latest block? Currently it is block 184,160. (Shows in the bottom right, hover over the icon, for 0.6.2).
Take just the first transaction in your list. Are you saying your client is at block 184,160 or greater and yet does not show a payment to that payout address for that specified payout amount (it should have at least 542 confirmations)?
