you can also use an anonymous array to accomplish what you attempted in your second example:
print [ split(/:/,<FILEHANDLE>) ]->[3]
Oddly enough, to use a list slice there are some subtle parenthesis issues:
# this works:
print ((split /:/, <FILEHANDLE>)[3]);
# doesn't work (note the missing outer parenthesis):
print (split /:/, <FILEHANDLE>)[3];
I'm guessing the second example has some ambiguity with taking the slice off the
print or the
split

Update: As pointed out below, an anonymous array is slower (by 39%) than a plain ol' list slice. Depending on the circumstances, however, it's very unlikely that this slowdown would ever be noticable (since on the box I tested, it was still able to perform 89,445 anonymous array creations and access per second).
