perl -e '($n = $_) =~ s/\.txt(\.out)$/$1/ and rename $_, $n for @ARGV' *
This is unsafe (as yours was) because a file "foo.txt.out" will be renamed
over the top of an existing "foo.out". To protect that, add this:
perl -e '($n = $_) =~ s/\.txt(\.out)$/$1/ and not -e $n and rename $_, $n for
@ARGV' *
