You do not need to be much of a shell scripter - it is just one line for each 

put in /usr/local/bin/mysql-3:

#! /bin/sh

mysql --socket=/tmp/mysql-3.sock

put in /usr/local/bin/mysql-4:

#! /bin/sh

mysql --socket=/tmp/mysql-4.sock

Make sure to exclude the ---- start/end marker lines when you paste, and fix the 
socket path if I guessed it wrong, if this is not obvious


chmod +x /usr/local/bin/mysql-3
chmod +x /usr/local/bin/mysql-4

Job done!
