It is possible to sort your data by any visible (or invisible) property.
In Report Builder, it looks like the data will automatically sort alphabetically by the first column of data.
If you'd rather sort by some other property, insert that other data item in your report, select that new data column and sort; then, delete that column of data and choose to retain the sorting. You will be prompted to do so.

Give that a try and let me know!
Thanks,
