I recently saw that CanPickUpLoot sometimes won't work. Mobs pick up drops from blocks and mobs, but cannot pick up thrown items.
To reproduce:
1. Spawn a zombie with enabled CanPickUpLoot (or enable it through /entitydata).
2. Drop an iron helmet under zombie's feet.
3. Zombie won't pick up it, even if PickupDelay is manually set to 0.

I checked MobGriefing and it was set to true.
Commands used:
/summon Zombie ~ ~ ~ {CanPickUpLoot:1}
/entitydata @e[type=Zombie,r=40] {CanPickUpLoot:1}
From https://bugs.mojang.com/browse/MC-49302?focusedCommentId=144131&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-144131
Used {{/summon Zombie ~ ~ ~ {CanPickUpLoot:1b}}}
Is MobGriefing set to false?
