Yes it is quite annoying.  After your help I tried various combinations
of (quote),(print),(string),(number-to-string) and (concat), both in the
TBLFM line and in the source block but found that this is the only way
to get a slightly unsatisfactory result:

| Days |     H:M:S |             |
|------+-----------+-------------|
|   29 | 236:30:00 | "236:30:00" |
|      |           |             |
#+TBLFM: @2$3='(print (concat "\"" @2$2 "\""))::@2$1='(sbe workingDays (hms @2$3))
