variable positioning

We have 15 variables for one report the variables like created by agent id, created by agent level, created by agent subgroup,transaction number etc. they are arranged in the sequence like

1.created by agent id,

5. created by agent level,

7.created by agent subgroup,

10.transaction number

The similar variables we want to arrange in a sequence

1.created by agent id,

2. created by agent level,

3.created by agent subgroup,

10.transaction number

Would there be any impact on performance, would there would be any impact on select statements in the backend.
