Solved this myself with a wild stab in the dark.

Looks like using {?;0;*} got the result I wanted, which is counter-intuitive, since I thought "?" only applied to single digits. In all the searches I made for proper mask syntax, this was non-obvious.

The * is for any pattern which includes none

for example {*;0;*} can return {0;1;1}, {1;0;1} and  {1;1;0}

Yup, if you want to ensure exactly one digit before any zero, then you can use {?;0;...

If you want to ensure at least one digit before the zero, then you have to use {?;*;0;...
