Note: files are images used in image processing.

Do not pass it the directory information: pass it the file names extracted from the directory information. For example,
dinfo = dir('*.tif');
filenames = {dinfo.name};
sorted_filenames = sort_nat_file(filenames);

Your could download my FEX submission natsortfiles, which was written to solve exactly this problem:
S = dir(..);
S = natsortfiles(S);

Your names look like this
s=arrayfun(@num2str,1:100,'un',0)
a=sort(s)
To sort them as you want
[~,ii]=sort(str2double(a))
out=a(ii)
