However, you are running with another resto shaman in the raid, therefore in periods in which a single tank takes damage, only one of you could use the shield effectively. You are also running with a disc priest and a holy pala, so the tanks probably have sufficient absorbs anyway, in which case it may make sense to use the higher ilvl item for more healing on the raid rather than the tanks.
