li works because it represents an integral number.
ld does not work because it represents a decimal number. Telling gnucash to 
expect a decimal number here wouldn't make sense, so number formats with such 
a format specifier are rejected. I wish gnucash would give a better hint as to 
whether the format passed in by the user is accepable or not. We're sometimes 
rather poor at guiding feedback :(
