The aux R. Eject relay needs to be watched during the saucer scoring sequence.
Does the relay stay pulled in once pulsed?
Does the relay drop out before score motor reaches the 4 cam?
Standing up the playfield may be needed to watch the relay.
Posting a snippet of the schematic of this relay coil and it’s hold in circuit would help.

Have you had any success since the online pinball clinic?

I tried to explain that the score motor cam 5 switch B is the top normally closed switch that is not making a solid connection allowing the relays to drop out too soon. A test of the relays hold circuits is to turn off the score motor service switch and momentarily close the saucer hole switches. Do the relays hold in consistently? Manually turn gears until cam 5 drops its switch stack. Do the relays release then?

Your info confirms that the score motor cam 5 switch B normally closed switch has a weak connection. Clean switch and adjust the top blade of the switch lower to insure a stronger switch closure, while still having a gap when open.
The problem with the special not releasing with score motor keeps running is on score motor cam 5 forward ( just right of cam 5). It’s normally closed switch is not opening properly when it’s switch stack drops keeping the relay closed. Adjust the top blade of the switch upwards slightly so the switch opens when the switch stack drops.
