I meant to answer this sometime back, but got busy.

The following general program mode template does what I think you want.

Code:

program:
	date = field('#original_date');
# compute the components
	year = subitems(date, 0, 1);
	month = re(subitems(date, 1, 2), '^\D*$',  '00');
	day = ifempty(subitems(date, 2, 3), '00');
# compute the return value
	strcat(year, '--', month, '--', day)

The trickiest part is the call to re. The pattern matches if the source contains only non-numeric characters, replacing them with '00' otherwise leaving them alone.
