Look in the init.lua file in your global config directory.  It will have this line:

    run_user_scripts_when_superuser = false

That's the default, so wireshark won't load your script when you do sudo.  It's done that way for safety, since  a Lua script can do basically anything it wants.

/me wonders why as a common user the LUA script is executed whwreas as sudo it won't print the hello world :

tfoerste@n22 ~/devel/wireshark $ cat hello.lua
- -- hello.lua
- -- Lua's implementation of D. Ritchie's hello world program.
  print("hello world!")

tfoerste@n22 ~/devel/wireshark $ ./tshark -X lua_script:hello.lua
hello world!
tshark: There are no interfaces on which a capture can be done


tfoerste@n22 ~/devel/wireshark $ sudo ./tshark -X lua_script:hello.lua
Running as user "root" and group "root". This could be dangerous.
