on the include_tax setting, I think you might be misunderstanding its use.
The include_tax setting does not govern whether the coupon will include tax in its output figure, but whether tax should be included in the total value that the coupon discount is calculated on.
Generally as discount coupons recalculate the tax anyway, you do not need to include tax. However the reason for the setting is that in some tax jurisdictions, a discount coupon can be sometimes considered as a fixed discount amount (much like a Gift Voucher) where tax is not recalculated, but the coupon may reduce the total order value including tax.
As for the penny difference you are seeing when using 10 items. I am not seeing this in my v139 code. (which contains fixes in a number of files to address rounding problems)
These changes have been posted elsewhere, but i'll try and come up with a definitive list.
N.B. haven't looked at the quantity discount prob you posted yet.
