Nicely done using Unix utils. You can have a pure sed solution (save the `ls` invocation) that is much simpler, albeit obscure, that hinges on the fact that every number has a `data.csv` file.
Given a sorted list of these files (through `ls` or otherwise) the following sed code will print out the data files for which A did not succeed on them.
/data/!N
/A/d
P;D
This works on the fact that there exists a data file for all successful and unsuccessful runs on data, so sed simply prints the files for which there does not exist an `A` counterpart.
If you want to only print out the numbers, you can add a substitution or two towards the end.

Edit: fixed the sed program
