There is no one "correct" order for Tarot suits that applies in all situations. There are several systems for suit ordering used by various people/decks. While one suit order is most common in the English speaking world, there are two others that are fairly common, and several more that come up now and again. I know of at least half a dozen suit orders used just among the various decks we offer and I am sure there are others I haven't run into personally.
Julie Cuccia-Watts has developed her own system of ordering the suits and the cards in relation to the ancient Egyptian calendar, the wheel of the zodiac, and the phases of the moon. She describes her system in a fair amount of detail in the included book. That system is reflected in the ordering of the suits in the Journey into Egypt Tarot app.
