Bibliography alphabetic ordering

Question

Again, I've faced the problem of bibliography sorting with no clue how to deal with it. The issue is in the fact, that the specific requirments for russian papers make me use custom-made style utf8gost705u.bst, as it is the only one, that fits the most requirments. However, there is an obligation for bibliography to be ordered in an alphabetical way, starting from cyrillic, which is not followed by thath biblio-style.

So it goes in this way:

\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
Some text \cite{}.
\bibliographystyle{gutf8gost705u}
\bibliography{name}
\end{document}


@article{Razumova,
title={Исламский Банкинг: Мировой Опыт и Возможности Для России},
author={Разумова, Ирина Анатольевна},
journal={Учебные Записки Международного Банковского Института},
number={11-1},
pages={157-166},   
year={2015},

}

}

@book{warde2000islamic,
title={Islamic finance in the global economy},
author={Warde, Ibrahim},

}

@article{bektax,
title={Исламские налоги как эффективный инструмент решения социально-экономических проблем в местах компактного проживания мусульман в России},

pages={480--490},

}

How to make it ordered alphabetically, from cyrillic to latin letters keeping on using the exact \bibliographystyle{utf8gost705u}?
