The tiers for spells is still a relatively new concept, introduced with ranks. We assigned most items to their respective tiers but we've yet to actually assign every spell to its tier so adding the filter now wouldn't help much.
Once we've assigned all spells to an appropriate tier, I'm pretty sure it'll be possible to add this as a filter on the web tools spells search. On the list, so to speak. But probably a long way off. The day we assign every spell a tier will be the day we likely lock all spells by rank (+-3 ranks) and we won't be doing that until we've properly addressed all level 70 spells (we're getting through each class one at a time).
