When defining a custom sexp via scripting - you can have paramateres be ships, numbers, variables etc. Is there a way to pass in a container (Map of string to int)? Otherwise, how do I access containers in a mission (or campaign file) given e.g. the name of the container?

There is currently no scripting support for containers.  So, unfortunately, containers cannot be used in scripted sexps.  It's a good idea though, so you should lobby a coder to add scripting support.  (If you posted a GitHub issue, it can be put on the feature request list.)

I have no idea how scripting works, so I never coded it and even if JG18 does know, I couldn't test it. But if scripting can access variables, we should be able to make it access containers too.

I'm very familiar with the Lua API code and not very familiar with containers. I'm guessing they are some kind of unordered map internally? I'd bet it'd be pretty trivial to add scripting support. +1 to putting the request on the ever-growing and ever-ignored issue tracker.
