When trying it out on the web version of HVTC, pressing 2 or 4 both played Pop Goes the Weasel, rather than 4 being the £100 win tune. Not sure if it just needs a minor code change as the player code at $3517 and $3523 (when decompressed) set the same X and Y values.
Changing the code at $3523 to:
$3523 LDX #$88
$3525 LDY #$9E
means that tune 4 is the £100 jingle as intended.
Hopefully @Luca that should be relatively easy to correct.

Oooh that's quite handy, to have report about HVTC stuff, I need more of them, because the archive has gone larger than I would have expected in my wildest dreams.
Thank you @Waz, missed two jingles there, so I took the leap to write down a better code for it too. Test it as it is now, and please someone name the exact cover for the £100 jingle.

Awesome find, thank you for sharing this in such great detail 
I quick verified this myself using your code, there is one tune missing from the HVTC file. But I suspect not for long, right @Luca?

| Vegas Jackpot - missing tune in HVTC
Good evening all,
Many years ago, when playing Vegas Jackpot, I managed to gamble all the way to win the £100 top prize (effectively four CHIP symbols in a row) and remember that you got a little jingle playing when you achieved this.
Upon doing a review recently, I managed to do the same achievement, and yes, the tune is there.
I did some looking into the code, and the main tunes seem to be called by setting the X and Y register with values and then doing a JSR $3300, with X being the start and Y being the end to compare in terms of note sequences, so what I can see from that is:
LDX 00 LDY 39 JSR 3300 - Game complete tune
LDX 40 LDY 5B JSR 3300 - Pop Goes the Weasel
LDX 60 LDY 88 JSR 3300 - Who Wants to be a Millionaire?
LDX 88 LDY 9E JSR 3300 - £100 win tune
LDX A2 LDY A8 JSR 3300 - little jingle before the nudge sound effects
May be useful if anyone is able to do a clean re-rip and update for HVTC?
