One thing to worry about is how you encode the arrays for transmission. If the array only contains simple strings without line endings, then writing each string on a separate line would work well. If the arrays could contain anything, then you need to use a more robust serialization format. I would suggest YAML.

Do you want the first script to run the second script? Or would having them run by an external process work? The Windows NT/2000/XP command shell will do pipes. 

command1 | command2

The advantage of the first script writing to stdout, and the second script reading from stdin, is that you can do different combinations: 
command1 > output.yml
command2 < output.yml
