Miners calculate the ranking of the transactions by BTC/KB. The lower it is, the lower the ranking it will be. Your transaction fee is 0.0001BTC and the size is 2947bytes, around 0.00003BTC/KB. The settings in the reference client indicates that fees below 0.00005BTC/kb will not get relayed unless the settings get changed. With lesser nodes willing to propagate your TX, not all miners would see it.
Next time you send a TX, make sure that you have a suitable fees/kb.
