Thank you! Unfortunately, all data is located in a separate database so I think cannot use these things wp provides. This example code in my post was just a mockup to demonstrate the issue. I guess I’ll just have to use get_row in both cases and then grab needed column value from there if requested.

Apparently, switching positions of these function calls doesn’t really change anything. They still don’t produce any effect whatsoever. And to be honest, I have only put all three of them for the sake of a code snippet demonstration in my post. There must me something terribly wrong with how and possibly from where I call them. Although, I’ve successfully used a bunch of other filters and everything works as expected and described in the WP codex.
