No, just that I am not getting what you are trying to prove here. The tags are all older than your chosen commit.

$ git-rev-list --topo-order ^v1.3.0 ^v1.3.1 ^v1.3.2 ^v1.3.3 e923eff

would show nothing -- and you propose to find out that commit is between v1.3.1 and v1.3.2 by using the information that the command gives an empty result but I do not know how?

$ git show-branch v1.3.1 e923eff v1.3.2

does show it is between these two, but that is because it avoids the 2^N permutations by using 1-bit per revision that it wants to check the reachability across.
