I would do this with a simple python script like the following.
I would add some code to make it more robust such as a try:
except around the n = s.rindex('.') in case the file didn't
contain a '.' character

#!/usr/bin/env python
import sys, os
for s in sys.argv[1:]:
    n = s.rindex('.')
    o = s[:n].replace('.', '_') + s[n:]
    if s != o:
        os.rename(s, o)
sys.exit(0)
