Dictionary Order Preserved in For In Loop?

I was trying to find an answer searching the internet and wasn't able to find anything. In Arcade when iterating through a Dictionary in a For In loop are the dictionary values iterated in order like an Array would? I remember in older versions of Python this was an issue if you wanted to maintain a specific iteration order on a dictionary. Wanted to verify with Arcade if this was the case. In the example below I would like the For In loop to always go through the Dictionary in the order I have established 1 thru 7. It appears to be working, but I wanted to verify. I suppose to be safe I could use an Array to establish a ordered key.

//Set the feature search distance

var dist = 100

//Create a Dictionary of Priority and FeatureSetByName

var dict = Dictionary(1,"SewerLiftStation",2,"SewerManholeVault",3,"SewerFitting",4,"CleanoutDevice",5,"MeterDevice",6,"ServiceConnection",7,"SewerGravityMain")

//Loop to search for features starts by searching for Priority 1 features if no features are found proceed to Priority 2 etc...

for(var p in dict) {

var lyr = dict[p]

var fs = Intersects(FeatureSetByName($map, lyr, ['assetid'], false), Buffer($feature, dist, 'feet'))

if(Count(fs) > 0) return First(fs).assetid

}

return "No Features Found Within" + " " + dist + " " + "Feet"

Thanks for any help with this.
