Well, it's played by children, and may be is the shorter one.
I think that one can fail even in the second "tiger" that way:
< un tigre, dos trigues... >
(the < u > of <gue> is ortographic and does not have sound).
in the third tiger one can fail in several ways:
<..., tres trigues >
<..., tres tigues >
<..., tes tigues >
<..., tres trigres>
or other ways.
Your second tongue-twister, yes, really a hard one.
