comment If $P(X_1 < X_2)$, what is $P(X_1 < X_2 \cap X_1 < X_3)$?
Hint: Can you compare $P(X_1 < X_2 \cap X_1 < X_3)$, $P(X_2 < X_1 \cap X_2 < X_3)$ and $P(X_3 < X_1 \cap X_3 < X_2)$? What is their sum? (Note that this is reminiscent of the case of two random variables, which can be solved by comparing $P(X_1 < X_2)$ and $P(X_2 < X_1)$ and computing their sum.)

Why repost the exact same question? To game the system? The trouble is that, now, posting the solution I reached would be to condone this behaviour...

No you cannot take any $\varepsilon>1$, actually you have to use $\varepsilon=-\log\mu$.

comment To test convergence of improper integral $ \int_{0}^{\infty} \frac{x\log(x)}{(1+x^2)^2}\, \mathrm dx$
The upper bound $\frac1{1+x^2}$ works like a charm on the whole interval.
