"tab-stop-list" is a variable which does not automatically became
buffer-local. This means that normally you only define the global value.
Fortunately you can make it buffer-local for the current buffer with
function "make-local-variable", so this is likely what you want:

(add-hook 'ledger-mode-hook
          '(lambda ()
             (make-local-variable 'tab-stop-list)
             (setq tab-stop-list '(4 56))))
