I fixed this issue by removing the content_type argument in the open call. I'm not sure if this could cause any side effects but our task queue for zipping files cleared up with no problems.
We want to migrate to Python 3 in the future but the App Engine Cloud Storage library doesn't support Python 3 nor does it seem like it ever will ( https://github.com/GoogleCloudPlatform/appengine-gcs-client/issues/78 ). I wonder if zipping multiple files like this is still possible using the newer google-cloud-storage library.
