First, it never makes any sense for a program to spawn a subprocess to run
/usr/bin/open. /usr/bin/open is just a wrapper around Launch Services. So,
you could just call Launch Services directly or use NSWorkspace, which is also
a wrapper around Launch Services.
Second, even using Launch Services isn't the best way to do this (sandbox
issues aside). It's better to run the equivalent of this AppleScript script:
tell app "Terminal"
activate
do script "your command goes here"
end
You can do that using NSAppleScript or the Scripting Bridge.
I don't know if this approach is more likely to work in a sandboxed app. I
doubt it, because it would be an enormous hole in the sandbox. If you can
direct Terminal to run arbitrary commands, what protection does the sandbox
provide?

I suspect you have a serious problem, then. You will probably need to deploy
outside of the Mac App Store so that you don't have to sandbox your app.
Alternatively, you can build a terminal emulator UI into your app and run the
embedded console program within that, instead of Terminal. Depending on the
needs of your console program, that may be a relatively straightforward
prospect or a very complex one.
