how to search and print the real path of a directory (which is version > 1.1)?

Question

Suppose the path x/y/z has 5 directories i.e.:

1.1
1.2
1.3
1.4
1.5

Now I want to print only those directory names which are greater than 1.1.

If in another path a/b/c the same directories are present, but 1.2 directory is missing, then it should print 1.3 as the next directory, which is higher than 1.1.

How to do that in tclsh?

The output should be like:

x/y/z/{version higher than 1.1}

For example:

x/y/z/1.2

or

x/y/z/1.4
