I don't know of this feature in Perl or Python; please provide some hint
if there is a feature like the one I need. Some code samples for
demonstration of your point are also welcome.

Python solution:

    import re

    items = \
        [
            "P1.HTM", "P10.HTM", "P11.HTM", "P2.HTM", "P3.HTM",
            "P4.HTM", "P5.HTM", "P6.HTM", "P7.HTM", "P8.HTM", "P9.HTM",
        ]

    print(items)

    print \
      (
        sorted
          (
            items,
            key = lambda f :
                tuple
                  (
                    (lambda : p, lambda : int(p))[i % 2 != 0]()
                        for i, p in enumerate(re.split("([0-9]+)", f))
                  )
          )
      )

output:

    ['P1.HTM', 'P10.HTM', 'P11.HTM', 'P2.HTM', 'P3.HTM', 'P4.HTM', 'P5.HTM', 'P6.HTM', 'P7.HTM', 'P8.HTM', 'P9.HTM']
    ['P1.HTM', 'P2.HTM', 'P3.HTM', 'P4.HTM', 'P5.HTM', 'P6.HTM', 'P7.HTM', 'P8.HTM', 'P9.HTM', 'P10.HTM', 'P11.HTM']
