This is surprising, I don't see why the telnet command fails.
But why don't you use the builtin telnet?
screen -S screen_cons -X screen -t node$i $i //telnet $tsv 20$i
Maybe you also want to turn on "zombie" mode for a console screen,
so you can still look at the window if the telnet connection dies.

You can also write a tmp file and then use
screen -S screen_cons -X source <tmpfile>
to source it. You won't have the reattach problem this way.
