could you please share your settings?

Sure! If you are using the "current" cperl-mode.el from git, you can do:

• Interactively: <M-x>cperl-set-style<RET>PBP<RET>
• In your Emacs config: (cperl-set-style "PBP")
• As customize option, file- or directory variable (which makes sense if you have different projects with different style requirements): Set cperl-file-style to "PBP"

For older versions of cperl-mode.el, here's the list of settings:

    ("PBP"  ;; Perl Best Practices by Damian Conway
     (cperl-indent-level               .  4)
     (cperl-brace-offset               .  0)
     (cperl-continued-brace-offset     .  0)
     (cperl-label-offset               . -2)
     (cperl-continued-statement-offset .  4)
     (cperl-close-paren-offset         . -4)
     (cperl-extra-newline-before-brace .  nil)
     (cperl-extra-newline-before-brace-multiline .  nil)
     (cperl-merge-trailing-else        .  nil)
     (cperl-indent-parens-as-block     .  t)
     (cperl-tab-always-indent          .  t))

In the end I stopped using perltidy

That reminds me of an issue "A command to run perltidy with the input from an emacs buffer" for which a first implementation never made it to Emacs....
