Collating sequence / sort

Can anyone explain to me why my spread*** sorts as follows. The cells are
formatted as text. This also happens with other similar data but I just cannot
see why. This does not seem to be either a test or numeric sort. In any
collating sequence I would expect all the T10's to be either before or after T1-
I just cannot see how it can be in the middle.


T10-02
T10-03
T10-04
T10-05
T10-06
T10-07
T10-08
T10-09
T1-01
T10-10
T10-11
T10-12
T10-13
T10-14
T10-15
T10-16
T10-17
