<p>I've heard that long time ago. Getblocktemplate or it's equivalent at that time reserved a small space on blocks for old utxos instead of following the rule of ordering transactions by its sat/Byte for the full block. ¿Does somebody have any information about it?.</p>

It seems 50kb of block space was reserved for high priority transactions: a tx with (Sum (Value of input \* Input Age) / Transaction Size) > 57,600,000

This seems to be a attempt to reserve a non-spammable space in blocks. Since equation above is a good heuristic to identify honest transactions.
