Bob,
I don't know of anything against it. I've used them. If you cock them at a slight angle to match the corrugation they hold pretty well. If you know the brand you might be using you can check with them and your local AHJ to see if there are any objections.
I did a search and came up with one Brands' info >
Minerallac They have their 1-1/4 x 9/16 staple being suitable for "3-Conductor (#10, #12, #14) Romex®, BX, MC and other cable"
