The underlying calculations are done using the Emacs Calc system. In
this system, : is used to represent ratios. If you want hours, minutes,
seconds, you need to use a different syntax. For instance, your table
could look like this:
#+begin_src org
|-------+----------|
| 1 | 0@ 53' |
| 2 | 3@ 12' |
|-------+----------|
| Total | 4@ 5' 0" |
,#+TBLFM: @3$2=vsum(@I..@II)
#+end_src
