The as-shipped storefront order-class doesn't include the numeric portion of an order-total's value when it recreates an order; that's what the storefront changes required by EO do.

Turn on the Edit Orders debug via its configuration setting, update that order again and send me a copy of the log (it'll be big) to my direct email address, which I'll PM to you.
I couldn't find where to turn on the Edit Orders debug. The only settings i have under configuration/edit orders are these: Click image for larger version.
