I don't understand how bitminter can win block 312400 and our find becomes orphaned.

That's 47 seconds later than us. I can understand if the time between two pools finding the same block is very short, but 47 seconds?
https://blockchain.info/block-height/312400Block timestamps should not be considered the actual times they were made. The timestamp for the block is part of your header data before you start hashing it, and is based off the pool server's clock. It also doesn't have to be updated as you continue to hash. Blockchain.info used to have 'Received time' vs 'Timestamp', but for the last few months that has been broken and they just use the timestamp for both.
I don't know about them but reading a previous post on the matter I would research any pool you are thinking about switching to as this could be effecting more than us. All I know is it sucks.
