Sorting does not work for numbers.

Sorting does not work properly for numbers.
If you have to sort 100, 200 , 2500,1500

the sorting result will be 100, 1500, 200 and 2500

It works for sorting only when are the numbers have equal digits counts. For example, it will work for 100, 300, and 200 because all of them have 3 digits but if any number has 4 digits like 1250 then sorting will fail.

Also, there should be ascending and descending sorting for number fields,

This is a major problem I intend to buy the premium features if you can resolve this problem
