You can change the language by swapping out the 1 in value='1' with the ID for the language of your choice. That number can be found by viewing the source code of the Post New Work page—just search for the language name and you'll see it. All that this script does is automatically select a different default choice for the dropdown, so if you want to use a different language only sometimes, you can still select it normally.
