Ensure Rules actions and conditions support price amount data entry by major units

When we switched to storing prices as integers in the currency's minor unit and converting them to the major unit on display, I believe we left behind usability in some of our Rules actions / conditions. Whereas before you could enter a price amount for comparison in major unit, now it only works in minor unit (at least in some places). It would be nice to be able to input prices as an administrator would expect in the major unit as on other price forms.
