Keypad_Read returns a value in the range 1-16, which uniquely identifies one of the (up to) 16 keys on the attached keypad. It's then up to your code to cross-reference this value with the legend printed on/next to the key.
At best, you could try swapping the row and column connections around so that RC0-2 connect to pins 1-3 on the keypad, and RC4-7 connect to pins A-D, but unless Keypad_Read is doing something unusual in its return value generation, this is likely only going to give you a 1:1 mapping between return value and key legend for keys 1-3 - I'm assuming that the return code is simply generated as (column + ((row - 1) * 4)), so for the 3 column keypad you've got, pressing key 4 (column 1, row 2) would then give a return value of 5, pressing key 7 would give a return value of 9, and so on...
