Well you can interface LDR directly on Analog Input Pins of Arduino with only simple voltage divider network, No need to use opamp/comperators...
as far as program is concern.... you need one more input to trig program to record sequence of events on sensors...otherwise order/sequence 123,231,321 is same and 132,321,213 is same...

Hope it helps,
