you should read the documentation of auto-mode-alist. it says quite clearly
that it is a list for specifying *major* modes. both longline-mode and
flyspell-mode are minor modes, and should therefore be specified in a
different way.
not explicitly stated, but still deducible from the documentation is the
fact that only the *first* matching regexp in auto-mode-alist is used. so
once flyspell-mode has been found, the list is not searched further
anymore.[1] this makes sense, because a buffer can only have one major
mode.
note that auto-mode-alist already specifies a major mode with files ending
in .txt, namely text-mode. your customisation therefore disables text-mode
for .txt files, which is probably not what you want.
to do what you want, you may add flyspell-mode and longlines-mode to
text-mode-hook:
(add-hook 'text-mode-hook 'longlines-mode)
(add-hook 'text-mode-hook 'flyspell-mode)
adding these two minor modes to text-mode-hook makes sure that they are
always turned on when text-mode is selected.
see (info "(emacs)Hooks") for details on hooks.[2]

Footnotes:
[1] note that add-to-list normally adds items to the front of a list, so
that flyspell-mode is indeed the first match found.
