The code-golf tag wiki excerpt says:
Code-golf is a competition to solve a particular problem in the fewest bytes of source code. If you want to score by characters instead of bytes, state this explicitly in the challenge. If source code length is not the primary scoring criterion, consider using another tag instead.
While byte count is a part of your score, it's certainly not the primary scoring criterion, so I do not think the tag applies.
The logic tag wiki excerpt says:
Logic questions tend to be questions on a logical process (working through a process with a logical algorithm) or boolean logic (AND, OR, XOR, NOR, etc.).
I'm not sure about this. While it is possible to create the output in your challenge using Boolean logic, one can also create it as
Finally, the restricted-source tag wiki excerpt says:
Imposes a restriction on the source code used to solve the challenge, for example, having no numbers in the source code.
This one definitely does not apply. A language restriction (or rather, creation date penalty) is not a restriction on the source code.
