I do not share Eli's position "all or nothing". I prefer graceful 
degradation and best result achievable with reasonable efforts.

However either the reason is performance or correctness, both variants 
are against modification of `string-collate-lessp'. I still think that 
Org will benefit from a compatibility wrapper with `downcase'.

The only additional consideration is that compare function should be 
configurable. If a user access same files from Linux and macOS then it 
may be really annoying to get different order of entries in agenda. For 
most of Linux users it is better to use more smart 
`string-collate-lessp'. Some care is required to sort entries obtained 
from multiple buffers in predictable environment (locale, case 
conversion table).
