Sort Files based on the number(s) on the file name

Experts

I have a list of files in the directory
Code:
mysample1
mysample2
mysample3
mysample4
mysample5
mysample6
mysample7
mysample8
mysample9
mysample10
mysample11
mysample12
mysample13
mysample14
mysample15

I would like to sort them based on the number(s) at the end and so far I have tried
Code:
printf '%s\n' mysample* | sort -t_ -k3n
printf '%s\n' mysample*|sort -t. -k4.2n

but Both sorts the files like the below order
Code:
mysample1
mysample10
mysample11
mysample12
mysample13
mysample14
mysample15
mysample2
mysample3
mysample4
mysample5
mysample6
mysample7
mysample8
mysample9

how should I tweak to get the correct result? ( i.e. 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)

Thanks in advance.

It is not nice but it works

Code:
printf "mysample%d\n" $( ls -1 mysample*|sed 's/mysample//'| sort -n )

Code:
printf '%s\n' mysample* | sort -k1.9n

Some ls implementations (the one from the GNU coreutils, for example) support the -v option (for natural sort of (version) numbers within text):

Code:
ls -v1 mysample*

For non-interactive use, drop the -1 option.
