bash scripting - editing files

How would you, for example, replace the number in the Nth column (columns are consecutive characters separated by blank space) of the line that contains "bleh" in the file called FILENAME with 12345?

Thanks.

Code:
#!/bin/sh

FILENAME="$HOME/file.txt"

mv -f ${FILENAME} ${FILENAME}.old
awk '/bleh/{$4=12345 ; print}' ${FILENAME}.old >${FILENAME}
