AWK in my usage of it only appears to evaluate the first number of the “20%”. so I ask; What usage of AWK should I implement to make 1 compare lower than 10.
Unix awk does not have strtonum but you don't need it, nor substr. The problem is that variables are treated both as string and numeric by the comparison operators. Trick is to typecast to numeric using (0 + expression), or to string using ("" expression), to force the right comparison. For a variable $3 like 17%, use x = 0 + $3 to assign the 17 part to x.
