Consider it, you have already answered your own question, jobs that require people who specialise in Lua, Python and Perl. A few years ago I remember looking at C++ and shaking my head saying I was fine writing C# and just didn't want to give C++ a go as I had practised C# a lot, and also C++ just didn't make sense to me. But you know what? In hindsight my train of thought back then was the way it was simply because I was not experienced enough to realise syntax is like flavours of lollipops, everyone has their favourite but they all get the job done as food.

As such, when the time comes you'll know what job you will want to be looking for because experience will tell point you in your preferred direction, so trust and give yourself more time to discover it.

At my last job, all the gameplay programmers (i.e. everyone except a few engine programmers) worked primarily in Lua.
However, they still wouldn't hire someone if they weren't competent in C and C++...

I also know of a few other companies where the game programmers work in python.
