If the ships are going to the same ports in a different order than the ports might be the same, but the itineraries are different. A ship that goes to ports A, B, C & D is on a different itinerary than a ship that goes to ports D, C, B & A.
Nonetheless, what you are describing is very unusual. I checked the March 2012 itineraries for these two ships and they are not the same. The Carnival Valor is doing six and eight night cruises while the Glory is just doing seven night cruises. What time frame are you looking at, because what you are describing is really unusual. In June 2012 the Glory is not in Miami (I believe it moves to NY). In September 2012 the Glory has still not returned to Miami. In December the Glory is doing the Eastern Caribbean on the 2nd, 16th & 30th while the Valor is doing the Western Caribbean on the 2nd, 16th & 30. The Glory is doing the Western Caribbean on the 9th & 23rd, while the Valor is doing the Eastern Caribbean on the 9th & 23rd.
Okay, I found it. Later this year the ships are doing what you stated:

These are not the same itineraries. Given the choice I would rather arrive in Grand Cayman early than late, so I like the Valor's itinerary better. Also, for what I would want to do in Roatan, the later arrival works fine, while the later arrival in Grand Cayman does not. Also, it is possible to miss Grand Cayman because it is a tender port (as is Belize). If you miss Grand Cayman the captain might try to arrive in Roatan early. The time for Cozumel and Belize are the same in both cases.
These are not the same itineraries, as noted above. Neither ship will be in the same port on the same day as other other ship. The different timing and different order does make a difference.
