Sort Mixture Of Numbers And Text Using Numbers And Decimals

I am looking for a VBA to sort rows which include actual numbers and text representing decomposed CTQs (or procedures in IT development)

Code:

Col A Col B
1Billing Accuracy
2Billing Time
3Credit Check Accuracy
4Credit Check Time
2.1Bill preparation

[Code]....

This is the order in which the data is copied and saved from worksheets in which they are developed. Note that 3 rows (8.1.2.1 through 8.1.2.3) are below 8.1.3 (because the three come from Worksheet 8.1.2 which came after worksheet 8.1). The first four rows came from a Top Level Worksheet. I would like to see them intermixed but in proper order.
