As suggested by karim79, I'll put my comment as an answer: what happens if you change the MIME type from application/octet-stream to application/zip?

Also, I see you're using a command line zip program, but you don't check for success of the zip, and also don't check if the file exists before attempting to send it out to the end users browser. Try hard coding a file name, manually using zip to guarantee a properly formed zip file, and then see if your code will spit it to your browser properly.
