org-table-sort-lines (numerically) leaves 0 separated

[Uwe Brauer]

Hi

I have the following table
| name  | marks |
|-------+-------|
| Auser |   0.5 |
| Buser |     2 |
| Cuser |     0 |
| Duser |     2 |
| Euser |     0 |
| Fuser |     3 |
| Guser |       |
| Huser |     0 |
| Iuser |       |
| Juser |     6 |

If I sort the second column numerically I obtain

| name  | marks |
|-------+-------|
| Cuser |     0 |
| Euser |     0 |
| Guser |       |
| Huser |     0 |
| Iuser |       |
| Auser |   0.5 |
| Buser |     2 |
| Duser |     2 |
| Fuser |     3 |
| Juser |     6 |

Which is bizarre, why is 0 not connected to the rest of the numerical entries?
