Personally, I would also use awk.
But here is a vim script version:
fu! <sid>Sum(colnr) range
let lines=getline(a:firstline, a:lastline)
let lines=map(lines, 'split(v:val)[a:colnr-1]')
call append(a:lastline, printf("total\t%02d", eval(join(lines,'+'))))
unlet lines
endfu
com! -nargs=1 -range SumCol :<line1>,<line2>call <sid>Sum(<args>)
