The first step should be to print the exact command line from your script, so that you can be sure that all variables have the values you expect: 
print "sqlldr userid=$u/$p\@$sid control=$fileParms[0] log=$fileParms[
+0] 2>&1\n";

If you can execute that by copy & paste to your shell, you should investigate further. What's in $rt after the run? Are the perl script and your shell in the exact same environment? Are the environment variables the same? Does sqlldr try to access the terminal? (fancy prompts or formatting characters).
