Please help, need help about tables

Hi sirs, goodday, i cant seem to find something related to table sorting and executing functions based on table contents numerical order.

I made script like this

Local vacantA = regionFindAllNoFindException(reg, "img.png")
Local vacantB = regionFindAllNoFindException(reg, "img.png")
Local vacantC = regionFindAllNoFindException(reg, "img.png")

Toast ("image found in A is " .. #vacantA)
Toast ("image found in B is " .. #vacantB)
Toast ("image found in C is " .. #vacantC)

I want to create table containing the counts of each vacant table, and then order them ascending, and execute a function based on what is highest to lowest, please help, im stuck with this
