If you redirect output to an interactive command from within a program, I would expect different results to having done it from the command line; but then I wouldn't do it, because it doesn't seem useful, but try this: 

open STDOUT, '| tee -i null | more';;
print "hello world! $_" for 1.. 1000; 
close STDOUT; 
exit;;
