This bug concerns the sorting of version numbers and the update function.

A) Sorting of version numbers:

1. In the EM, select "Import".
2. Enter ameos_formidable.
3. In the search result, click on the extension title.
4. Next to "Load details", open the drop-down list with the version numbers.

Expected result:
...
0.7.0
0.8.0
1.0.0

Actual result:
0.7.0
1.0.0
0.8.0

B) the update mechanism

1. Install ameos_formidable 0.7.0.
2. In the EM, select "Check for extension updated".

Expected result:
The updater offers to update ameos_formidable to the latest version 1.0.0.

Actual result:
The updater offers to update ameos_formidable to the no-latest version 0.8.0.

When ameos_formidable 0.8.0 is installed, the updater show ameos to be up-to-date.

Interestingly, when you use import_extensions with 0.8.0 installed, the result list will show you the green "update" icon, allowing you to upgrade from 0.8.0 to 1.0.0.
