That looks like a terminal init string, probably generated when
readline is initialized.  Does it disappear if you do

  octave -q --no-line-editing script.m > a_file

?  Another option would be to set your TERM environment variable to
something that doesn't have an init string.  Maybe

  TERM=dumb octave -q script.m > a_file

BTW, 3.0.0 is obsolete.  You might consider upgrading to 3.2.0.
