Yes you can create loot filters for rares. Just the way you did in your example.

.dual:
For example:
([AS%].dual + [CRIT%].dual + [CRITDMG%].dual)
will return 3 if the item has all these three properties
will return 1 if the item has only one of the three properties
will return 0 if the item has none of these properties
