alphanumeric sort in VIM

Suppose I have a list in a text file which is as follows -

TaskB_115
TaskB_19
TaskB_105
TaskB_13
TaskB_10
TaskB_0_A_1
TaskB_17
TaskB_114
TaskB_110
TaskB_0_A_5
TaskB_16
TaskB_12
TaskB_113
TaskB_15
TaskB_103
TaskB_2
TaskB_18
TaskB_106
TaskB_11
TaskB_14
TaskB_104
TaskB_112
TaskB_107
TaskB_0_A_4
TaskB_102
TaskB_100
TaskB_109
TaskB_101
TaskB_0_A_2
TaskB_0_A_3
TaskB_116
TaskB_1_A_0
TaskB_111
TaskB_108

If I sort in vim with command %sort, it gives me output as - 

TaskB_0_A_1
TaskB_0_A_2
TaskB_0_A_3
TaskB_0_A_4
TaskB_0_A_5
TaskB_10
TaskB_100
TaskB_101
TaskB_102
TaskB_103
TaskB_104
TaskB_105
TaskB_106
TaskB_107
TaskB_108
TaskB_109
TaskB_11
TaskB_110
TaskB_111
TaskB_112
TaskB_113
TaskB_114
TaskB_115
TaskB_116
TaskB_12
TaskB_13
TaskB_14
TaskB_15
TaskB_16
TaskB_17
TaskB_18
TaskB_19
TaskB_1_A_0
TaskB_2

But I would like to have the output as follows - 

TaskB_0_A_1
TaskB_0_A_2
TaskB_0_A_3
TaskB_0_A_4
TaskB_0_A_5
TaskB_1_A_0
TaskB_2
TaskB_10
TaskB_11
TaskB_12
TaskB_13
TaskB_14
TaskB_15
TaskB_16
TaskB_17
TaskB_18
TaskB_19
TaskB_100
TaskB_101
TaskB_102
TaskB_103
TaskB_104
TaskB_105
TaskB_106
TaskB_107
TaskB_108
TaskB_109
TaskB_110
TaskB_111
TaskB_112
TaskB_113
TaskB_114
TaskB_115
TaskB_116

Note I just wrote this list to demonstrate the problem. I could generate the list in VIM. But I want to do it for other things as well in VIM.

With [n] sorting is done on the first decimal number
            in the line (after or inside a {pattern} match).
            One leading '-' is included in the number.

try this command:

sor n

and you don't need the %, sort sorts all lines if no range was given.

EDIT

as commented by OP, if you have:

TaskB_0_A_1
TaskB_0_A_2
TaskB_0_A_4
TaskB_0_A_3
TaskB_0_A_5
TaskB_1_A_0

you could try:

sor n /.*_\ze\d*/

or

sor nr /\d*$/

EDIT2

for newly edited question, this line may give you expected output based on your example data:

sor nr /\d*$/|sor n
