opps, sorry, typo. Fricas "did not" do 5.

Sure. A quick look shows that of those solved, #5 by Rubi and Maple had non-elementary anti-derivative (Elliptic function) in them. This is the one Mathematica, Sage and FriCAS did not give an answer for.
In #6,#7,#8,#9 Mathematica gave non-elementary anti-derivative (also using Elliptic functions).
If I overlooked something, please feel free to correct, all other anti-derivative are using elementary function as far as I see (exp, log, radicals, trig and inverse trigs and +,-,/,*)
Here is an updated score table using your proposed notation:
1. Mathematica: did 1,2,3,4,(6),(7),(8),(9),10 did not: 5 2. Maple: did 1,2,3,4,(5),6,7,8 did not: 9,10 3. Rubi4: did 2,4,(5),6,7,8,9,10 did not: 1,3 4. Sage: did: 1,2,3,7,9 did not: 4,5,6,8,10 5. Fricas: did 1,2,3,4,6,7,10 did not: 5,8,9
ps. I moved Sage's 4 from the "did" to the "did not" since the answer still contained another integral in it, so to be fair to other CAS's it should have been counted as "did not". sorry Sage :(
