According to a dictionary, all these words are quite synonymous. Is there any subtle difference in meaning?
I consulted the Free dictionary and found that:
scarce: Hard to find; absent or rare.
rare: Infrequently occurring; uncommon.
uncommon: Not common; rare.

All three talk about frequency of occurrence for something within a population of things
does not occur as often as
does not occur as often as
"scarce" has more of an absolute meaning of "hard to find or obtain" sometimes do to very high demand or very low supply
If you say something is "uncommonly good" it means it is "more than very good", however, if you say something is "rarely good" it means it is "not often good" or "usually bad".
