Fixed in 14w02c, just tested.

Okay, it appears the root tag is in fact 'tag', it was working before for some reason. Now I can confirm this issue in 1.7.4.

It is the proper way, check the written book tag. Unless I am mistaken that the root tag here is not '' but 'tag'.

It's invalid because it no longer is a problem with 1.7.4. Try

/give @p minecraft:written_book 1 0 {tag:{pages:["Fail: here"]}}

This looks like an improperly formatted string for a book, as the correct NBT formatting would be

{tag:{pages:["Fail: here"]}}

Also, doTileDrops doesn't prevent at least one of the problems: music disks from jukeboxes. With doTileDrops on, they still come out of jukeboxes filling up the creative inventory.

Steps to reproduce:
1. Get a jukebox and music disk.
2. Place the jukebox on the ground.
3. Insert record disk.
4. Break the jukebox.
5. Receive an extra record disk!

The other one I can find is item frames still drop themselves and their block when destroyed in an unorthodox way. (I'll post how to do it if anyone wants)

I believe it should be relatively easy to just add a check for creative when dropping blocks or using the method that the gamerule does, only do it for the player that broke the block. Latter may not be as easy to implement.
