Try using the split string method and then the insert list method.

Untested code:

###
infile = file("in.txt")
outfile = file("out.txt")

for line in f:
     columns = line.split("\t")
     columns.insert(4, "0")
     outfile.write("\t".join(columns)+"\n")
###

The code might not be perfect, but you get the idea.
