Does your calling script do anything after the script call?

What happens (as far as we can tell) is:
Main script calls script 2
Script 2
preforms action
exit 0 (success)
Main script can get return status (exit 0) of the called script
Main script either performs other tasks below your task selection code (if there are any) or exits.

You can use the exit status of the called script to take additional actions in the calling script.

Shell scripting tends to be pretty linear in that when one command completes, the next will start. Running another script, from the perspective of your main script is just like any other command.
The task selection code you provided only allows for one task selection, then it is done.

If your intention is to remain in the main script's task selection code, then you need to write a loop around the task selection code and add an exit item to your task selection code.

As stated by Corona688, removing the exec leaves your main script running, and the command to run a second script returns as expected. What happens then is up to the code in the main script.

NAME

       script - Makes a transcript of terminal session

SYNOPSIS

       script [-a] [file]

       The script command makes a transcript of everything printed on your terminal.

OPTIONS

       Appends the transcript to file rather than writing it to file.

OPERANDS

       The name of an output file that will contain the transcript of the session.  If this parameter is omitted, the file typescript is written.

DESCRIPTION

       The transcript is written to file, or appended to file if the -a option is given.  If no file name is given, the transcript is saved in the
       file typescript.

       The script ends when the forked shell exits.

       This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create	an
       example of a working session this way).

       If you specify the -a option and the file does not exist, it is created.

       If you do not specify the -a option and the file exists, it is replaced.

RESTRICTIONS

       The  script command requires a streams based terminal.  In single user mode, streams may not be enabled.  Under these circumstances, script
       will exit with no action.  If you are the superuser and need to run this command in single user mode, use the  following  special  instruc-
       tions.

   Enabling Streams
       If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams.  This command is avail-
       able to the superuser only.
