Finwitch:

Few ideas:
1) Macbethian solution: The spell is not cast at the CLOAK, but at
humans/surroundings in general... Like some sort of heat-camera or
echo-scan, only a specified spell.

2) It works for Dumbledore, because he's using Elderwand that's
unbeatable.

3) Dumbledore has knowledge that the Invisibility Cloak could be in
use there.

4) The spell may detect and magnify sound of human breath - so
Dumbledore knows how many humans and where in the room there were...

5) Maybe it's a spell only Dumbledore (and JKR) know about? Maybe it
was Aberforth's invention when Albus became invisible during their
play of hide-and-seek?
