Uhh! Are you trying to obfuscate your code?

The following looks much clearer. Do you not agree?

    result = self.Catalog(year_of_birth_index =
                          {'query':[1000,1500], 'range':'min:max'}
			  ):
    print len(result), 'objects found'
    for i in range(len(result)):
	proxy = result[i]
        print i, proxy.title, proxy.getObject().year_of_birth

This will give you a string but you need a list.
This means that your action must convert the string into a list
probably by splitting at ",", stripping and converting to "int".
