Except there isn't any problem here whatsoever. Yes, it's coupled, but it doesn't matter. No, this kind of code doesn't scale. It doesn't have to.

The time you spent writing this comment was longer than what it took writing this code. Considering what kind of site this is, that code may work indefinitely. Or, if necessary, someone from the future will need to change that 3 to a 4 at some point. In terms of total cost, it's almost certainly the cheapest solution.

They'll figure it out. They're a programmer, figuring things out is their job.
