you have to play with word boundary. check your sed man/info page for more info. alternatively, the logic to do this is to iterate each old, check for "old" and when found, change it to "new".. so in bash, you can do something like this, assuming your words are in a file
Code:
#!/bin/bash
declare -a arr
while read -a arr 
do
    for ((i=0;i<=${#arr};i++))
    do
       case "${arr[i]}" in
            old) arr[i]="new"
       esac
    done
    echo "${arr[@]}"
done < file

output
Code:
$ more file
old gold fold old
$ ./shell.sh
new gold fold new
