You could "print" the value to the standard output in script 2:
print $PID or echo $PID
In script1 get it to a variable:
tmp=`script2 p1 ...`
The tmp variable will have your value.
You can do the same if you have to return more than 1 value.
They will be all in the tmp variable separated by space. To use them put them into "parameters" (don't forget to save true parameters of script 1):
set $tmp
Now $1 will have the return value 1, $2 - the return value 2, etc.

envstore
ENVSTORE(1) BSD General Commands Manual ENVSTORE(1)
NAME
envstore -- save and restore environment variables
SYNOPSIS
envstore command [args ...]
DESCRIPTION
envstore can save and restore environment variables, thus transferring them between different shells.
command must be one of
clear
Forget all stored variables
eval
Produce shell code for evaluation, restoring all saved variables
list
List saved variables in better readable format
save variable [value]
Save variable either with its current shell value or with value
rm variable
Remove variable from store
Note: Only the first character of command is checked, so envstore e instead of envstore eval, envstore c for envstore clear, etc., are also
valid.
ENVIRONMENT
ENVSTORE_FILE The file in which the environment parameters are stored, /tmp/envstore-EUID by default,
LIMITATIONS
Variable names or values must not contain null bytes or newlines.
Due to limitations imposed by most shells, it is not possible to save parameters containing more than one consecutive whitespace. envstore
will save and display them correctly, but unless you do IFS trickery, your shell will not be able to load them.
The current maximum length (in bytes) is 255 bytes for the variable name and 1023 bytes for its content.
AUTHOR
envstore was written by Daniel Friesel <derf@derf.homelinux.org>.
Original idea and script by Maximilian Gass <mxey@ghosthacking.net>.
