There's no API reference indeed. You could open an issue request regarding this on Apps Script issue tracker. But deducing from what the code-completion shows, here is my understanding:

var folder = DocsList.getFolder('path/to/folder');
var files = folder.getFiles();
var blobs = [];
for( var i in files )
  blobs.push(files[i].getBlob());
var zip = Utilities.zip(blobs, 'newFiles.zip');
folder.createFile(zip);

But I have not tested this code, so I don't know if it will work. Also, it may work only for files not converted to Google's format, or maybe only for those or a subset of it. Well, if you try it out and find something, please share here with us. One limit that you'll sure face is the filesize, it will probably not work if the zip file gets "too" big... yeah, you'll have to test this limit too.
