Very easily using my FEX submission num2words:

http://www.mathworks.com/matlabcentral/fileexchange/47221-number-to-words

Easy to use, plus options for customizing the format, case, scale, sig-figs, etc:

>> num2words(0)
ans = 'zero'
>> num2words(1024)
ans = 'one thousand and twenty-four'
>> num2words(-1024)
ans = 'negative one thousand and twenty-four'
>> num2words(1024, 'pos',true, 'case','title', 'hyphen',false)
ans = 'Positive One Thousand and Twenty Four'
>> num2words(1024, struct('type','ordinal', 'case','sentence'))
ans = 'One thousand and twenty-fourth'
>> num2words(1024, 'and',false, 'order',1) % round to the tens.
ans = 'one thousand twenty'

I would approach it this way:

nc = {'one' 'two' 'three' 'ten' 'fifteen' 'twenty'};
n = 23;
out = [nc{6} '-' nc{3}]

You will have to create your own full cell array and figure out how to parse the number and do the necessary cell array referencing, but this should get you started on one way to do it.

I don't know how many these go up to, but assuming it's only fifty or so, I'd just call dir for each word and concatenate all the results. Sure it's 50 lines of code but that's not many and it's easy and straightforward. You can just toss all the lines into a function or something - no big deal and simpler than trying to use regexp or sort (as you already know).

folder = pwd; % Can be whatever you want.
files = dir(fullfile(folder, 'one*.*'))
files = [files; dir(fullfile(folder, 'two*.*'))];
files = [files; dir(fullfile(folder, 'three*.*'))];
files = [files; dir(fullfile(folder, 'four*.*'))];
files = [files; dir(fullfile(folder, 'five*.*'))];
