This might help.

[The script screen-test.sh runs the secondary script]
  NB: nothing gets output in the screen session window itself
  - if you want that then use tee
      2>&1 | tee $TMPFILE


#  cat screen-test.sh
#!/bin/sh

# Send command to screen session
# - if you have more than one screen session, you'll
#   need to find out the right session and use it
#   specifically.
#screen -r 10345.root -X exec ${PWD}/screen-test2.sh
screen -r -X exec ${PWD}/screen-test2.sh

# Give job time to complete before continuing....
sleep 1

# Get output file name (was created in other script with mktemp)
MYFILE=$(ls -rt /tmp/screen-test.*|tail -1)

# Display file and remove it
cat $MYFILE && rm $MYFILE



#  cat screen-test2.sh
#!/bin/sh

TMPFILE=$(mktemp -p /tmp screen-test.XXXXXX)

(
echo "+====+ $TMPFILE +====+"
echo "Running in dir: $(pwd)"
echo "-----------------------"
# command(s) to run in session to create desired output
/bin/ls
echo -e "======================="
) 2>&1 > $TMPFILE
